If neither Sally nor myself feels quite right for you, then I suggest you browse the bookstore or even the public library for books published in the last few years that remind you in some way of yours. Check the Acknowledgments page to see if they thank an editor. If not, see if there is any information to contact the author and ask if they used a freelance editor and if so, would they recommend them.

The result will be a very clean and much improved manuscript, but with lots of comments and suggestions, which will probably require some rewriting and extra work on your part. Getting back a heavily edited manuscript like this can be challenging, but know that it will drastically improve your writing skills and help you identify your weaknesses. During the revision process, it’s possible to create new consistency issues, which is why we recommend a final proofread or at least some beta-readers to help finalize your manuscript.
Definitely not unreasonable, Frank. However, you have a couple of options. Rather than pay for a full developmental edit on what you have written so far, you can ask the editor to do a manuscript assessment – which includes a detailed written report. An MA is usually done for a fixed price based on the word count. Alternatively, you could ask the editor to do a sample/developmental edit on one chapter only. Using track changes, they can go through and make edits and comments. It’s good that you are already thinking of hiring an editor before you complete the MS. It will help guide you with the other 40% and revisit what you’ve written so far, so that once you are finished, the MS will be in much better shape for the next stage of editing.
Moreover, the casual distinction between a (developmental) “editor” and a “copyeditor” can be a bit simplistic, particularly in a self-publication or even vanity-publishing context. A self-published author may barely have the budget to hire one editor, so that editor needs to be able and willing to blur the lines between developmental editing and copyediting. The editor must also be accustomed to working with authors of a variety of strengths and weaknesses, including many whose work would not, in fact, have been accepted by a commercial publishing house in its current form. I have come to take great satisfaction in taking a new or newish author by the hand and helping them find ways of making their work the best it can be. Of necessity, this must include line-by-line correction of grammar and style (often a surprisingly great amount of such correction), but can rarely be limited to that.
Are you writing a picture book? A chapter book or easy reader? Is your book for middle grade readers or young adults? You may not know for sure! What age groups will be reading your book? How many words should your book have to be age appropriate? What themes or topics are typically relevant? These are some of the more generalized questions your editor can answer for you.
After writing some of the book or a first draft of a book, some authors decide that they need more than an editor; they need a writer to take their writing to the next level, in order to get published or reach the level of sales they aim for.  I can refer aspiring authors to excellent, experienced co-writers, book doctors and ghostwriters, some of whom have worked on New York Times Bestsellers and other award-winning books. Find out more about ghostwriting services.

I am not without sympathy when some new authors get “sticker shock” upon hearing an estimate for my editorial services, and I am actually relatively affordable. (Most reasonably well-written novels would not cost even close to $3000 for me to edit, let alone $5000.) I also offer generous installment plans and discounts for bundled services. But there is a limit to how low I can go.

Additionally, I think that many GREAT, very reputable editors absolutely will not complete a sample edit for free. They can point you to their work, their testimonials, and their references, though, free of charge. And if you’re curious why editors I know do not offer a free sample edit, check out this video to illustrate the point. https://youtu.be/essNmNOrQto

Next, it is possible to follow the road to traditional publication without hiring your own editor, with editing being done at the publisher’s expense. However, you have to be a very good writer and self-editor to get on that road, and what you write has to fit into a very marketable niche. You also need to be very patient and willing to weather plenty of rejection along the way. Don’t jump too quickly to the conclusion that this option is closed to you. Do your research carefully. There may be a small press that is just right for your book and that will be happy to help you make it the best it can be while paying YOU rather than making you pay them.

Excellent advice, Teymour. I’ll add this food for thought if I may… ANYONE CAN WRITE. Few people write well. Even fewer can tell a good story. IF YOU CAN TELL A GOOD STORY, and you’ve been working on a book but your writing skills are a little rusty, you need an editor who actually cares about your success, who cares about making your book the very best it’s capable of being. That usually takes an editor who instinctively goes above and beyond what’s expected. Every single author, every single story is unique. Each deserves the undivided attention of the editor.… Read more »

About 25% of my (fiction) editing work is direct with authors, and the rest is split between two publishers. It my be of interest to note that these rates are close to what publishers pay their editors. That is to say, if you, as an author, were to traditionally publish your book, you would be paying this amount via royalties. Creating a professional product via self-publishing is not cheap, the costs (and income!) just shift from the publisher to the author.
It’s best, if you decide to hire a freelancer, to figure out what the going rate is for the service you need, and expect to pay that amount. Otherwise it may turn out to be a waste of money, because the quality of the service will suffer. Sometimes there are payment plans to help with high costs! But it’s really a good investment to pay industry standard for editorial services; I agree with Shayla.
Having your manuscript reviewed by a professional book editor is a rewarding experience. In addition to the improvements to your manuscript, you will also benefit from the feedback on your writing that only a finely tuned professional editor can provide. Writers often comment on the lifelong benefits enjoyed from their very first editing experience. If a writer wants to ensure they are creating an impactful and enjoyable reading experience for their readers, then editing is a no-brainer. Remember nothing is more damaging to your author brand that publishing a book with embarrassing typos and grammatical errors. Read more.
Editors’ fees vary so drastically that authors are often (rightfully) confused about how much to pay. I’ve seen copyediting fees that range from $20/hour to $300/hour. That said, I’ve seen plenty of authors pay $20/hour for a poorly executed copyedit that needed to be redone. I know one author who paid $200/hour for a copyeditor who’d worked on a famous best-seller, operating under the false assumption that a good copyedit would be their ticket to best-seller status. That didn’t happen. Get a few bids and consider paying a couple different editors for two hours of their work and compare. It’s important to judge the work rather than the fee. Consider this investment as research rather than money wasted.
I was recently directed to your excellent article from almost a year ago by a colleague at SouthWest Writers in Albuquerque, New Mexico. As a freelance literary editor of memoir, poetry, and novels, I offer authors guidance and support similar what you describe, but of course I cannot handle editing every genre. I was gratified to know that I’m doing the right thing by sticking to my specialties. By coincidence, someone who reached out to me last week on LinkedIn was looking for a children’s book editor and one of your readers in this conversation recommended one. That reminds me… Read more »
Working with a professional is always the best choice, so if possible, then save up to work with an editor. But of course, some writers can't afford this, in which case there are some other options. You can barter with other writers in the same genre, editing each other's work, or providing other services you might be more skilled at e.g. Marketing tasks.

Some authors budget very unrealistically, perhaps just a couple hundred dollars. (I’m not saying this is necessarily true in your case, but I have encountered it.) In such cases, I find myself wondering whom they are imagining should bridge the gap between what they are comfortable paying and what the editor needs to earn in order to pay expenses and support him- or herself.
You know, Rob, I’ve learned people offer their services for pay for a variety of reasons, and they live in a variety of circumstances. Some do it just to make a little side money, because they love the creativity…it’s not everyone who’s doing it because it’s their main livelihood. Others are new to the field and don’t feel they can command more. And sometimes, maybe you connect with someone who’s affordable, but they still do a great job.
Developmental editing (may also be called structural or content) – looks at the book’s big picture and overall structure in nonfiction or plot and characters in fiction. Developmental editors may assess a book idea, outline, or early draft to tell authors what works and what could be better. The big picture questions need to be answered first before an editor ensures your words are polished and used correctly.
Obviously there is a big difference. I actually started with screenplays (with some mild success) partly due to hearing that as long as you have a good story, the grammatical errors won’t be a big deal. Well, that was not true. Maybe if a producer liked the story or I was already established but every contest I entered always came back with feedback about the grammatical errors. Even if I won or placed as a finalist, I always received critique on that. Very little is spelling error, it was more about structure, etc.
