If “the greatest benefit of an editor is that he is she is not the author—the editor is someone else,” then an editor is no more than a beta reader, and all authors would need is friends to read their novel and give feedback. I recommend beta reads before a book is sent to me for editing, because casual readers, approaching the story fresh, can indeed find flaws in the book the author is too close to the story to see. But it’s after the beta reads that a professional editor steps in to do her magic. A skilled fiction… Read more »
As for multitasking, believe it or not, I try to schedule so that I am only working actively on one book at a time. Research keeps showing that “multitasking” is actually less efficient, because of the time lost to leaving behind one task to restart another. (Think of it this way: If you take on two clients at once for work that would take one week each with your full attention, either you can tell both clients the work will be done in three weeks because you’ll be alternating between them, or tell one client it will be done in one week and one that it will be done in two weeks, because you’ll complete one before you start on the other. Which of those makes more sense?) Obviously, with back-and-forth communications, sometimes complete “monotasking” is impossible, but I think it should be considered the ideal.
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.

A place you can post your job and hire freelance editors. With nearly 60,000 editors on the site, however, it can be a daunting project to find the right editor. To narrow down the candidates, you could make a detailed project description with required skills, language competency, and portfolio requirements. This should help eliminate unqualified editors. You can also include a random requirement like “Respond with ‘Hey, Jedi!’” in to find those detail-oriented editors who actually read your entire post and follow directions.
The U.S. Bureau of Labor Statistics states that employment of editors is expected to have little change up to 2026, as print media continues to face strong pressure from online publications. Editors who have adapted to online media and are comfortable writing for and working with a variety of electronic and digital tools will have an advantage in finding work. 
Start at the top of the copyright page and work your way down. Copyright pages can be formatted differently, but they usually start with the publisher, date, and location of publication. Slowly scan each line to look for an editor’s line listing. The editor (or group of editors) are usually listed in the middle, underneath the publisher’s information, but above the country and printing number.[3]
I implemented this way of working years ago and see how empowering it is for authors, and helpful for editors to boot. This doesn’t mean you’re asking your editor to do a free sample edit. (I discourage editors from doing this and caution authors who push for it as asking editors to work for free before you hire them may result in resentment.) Paying an editor for a few hours of their time to ascertain whether they’re a good fit for you is a great way to put your toe in the pond before submerging yourself. You can then see for yourself if the editor’s suggestions and comments resonate before moving forward with the whole project.
Start with a google search and see what comes up. Click on a handful of options and see if you can find an editor who is specialized or who has edited books similar to your own. An easy way to do this is to open just a few of your favorites in tabs and check out each editors’ website and about me section. Take a look at their testimonials. See if any stand out to you.

ROUND TWO: an in-depth, comprehensive, line-edit that includes rewriting sentences, improving word choice, organization, plotting and pacing. We’ll make the dialogue stronger and more believable, the action more tense and nail-biting, and the emotional peaks less melodramatic and cheesy. For non-fiction, we’ll strengthen your argument and make the writing more engaging.
I am an author of a book “In From the Dark” that was written and published in 2010; I have two other books I need to complete however, I was wondering if my first book could be re-edited and if I could get assistance with the second one as well. I am not to happy with the editing assistance i’ve previously received yet, because I was new at the time, I didn’t know what to look for. Please someone help if you can. My book can be found at barnesandnoble.com. I have not done any marketing or anything with the book since 2011 and was hoping once the second one is complete I can then push the both again.
If an editor’s rates seem skeptically low, send an editing test, ask for references or a sample, place a hidden message in your post, and see if they understand the different types of editing. If an editor passes all of these tests, even if she’s a newbie, give her a try. This could save you hundreds of dollars and help you find a skilled editor who is competent and affordable.
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.
