In addition to the individual editors listed above, the Reedsy marketplace is full of vetted professional editors for every editing level and genre. They screen their editors and only allow the best of the best to be listed on their website. I'm a BIG fan of them because they have made the process easy for me to find the best book editors, book cover designers, and even writers to help me with my projects.  Talk about awesome!
I’m sorry you feel that way about my participation in the discussion and defending editors of similar background to myself from what I considered unwarranted disparagement. Perhaps the only approach that would have 100% proof against accusations of “trolling” would have been to allow the claims to stand unchallenged, but that did not seem fair to people who come here to get useful information.
Good article. I especially like to see mention of the different types of editing. I find that a lot of new writers don’t know this; they get a copy edit and think everything is nicely edited only to discover once they’ve published that people are saying the book needs a good edit. That’s because it needed developmental and line editing as well. I often find that indie books could do with a line edit. I think it’s the most neglected area of editing.
I find many of these responses by Trish to be unethical trolling for business on another editor’s conversations. Trish may be an excellent editor, but her actions here leave me speechless. I agree with a lot she says, but what if her dealings with me are as unethical as her trolling here. I expect expertise and experience from my chosen editor. But, before that, I expect a high ethical standard and professional interaction on the web.
#2. YOUR BEST BOOK: nearly every other copy editor or editing service focuses on the writing and the mistakes. They will improve the flow of the words and sentences, and they will make it better, but they won’t fix the major problems with content. Our editors have been trained in the Write Good BooksTM method to make sure your book is commercially sound and will resonate with your audience on a deeper level. For nonfiction we focus on branding, credibility, trust, so your readers will take action and see results. For fiction, we focus on universal story telling principles, plot structure, dramatic tension and suspense, and world-building. Because a clean book isn’t always a good book.
Editors are an integral part of content generation at any level. A quality editor is responsible for the final, polished look and feel of any written content produced by a client. Freelance editors provide a flexible and talent-driven way to manage multiple products in a professional way. They can be used for a wide variety of projects, from editing for syntax and grammar on regular blog posts to providing structure, pacing, and style feedback for nearly finished novels.
I immediately noticed upgrades to certain passages that had hung me up. There are quite a few spots that I had rewritten over and over again but felt they were just not quite right and you seemed to find them all and make them flow perfectly in no time! I am very excited with the new work that you have placed before me. Again, excellent work and thanks. Looking forward to continuing to work with you!
Technology may have changed the way books are produced and distributed, but ultimately the connection between reader and writer is one of the most enduringly personal in history. You need to pay close attention to an editor’s manner and decide if the relationship is likely to be pleasant, professional, and productive. Is the editor overly curt or slow to respond to your emails? If the comments in the sample edit are too harsh, how will you make it through hundreds of pages of red-inked barbs? Beyond the financial expense, editing can be an intensely emotional journey; make sure that your editor will be a good travel companion.

An edit is a business transaction. This means that money will exchange hands. Therefore, you need to approach the edit as both a writer and a businessperson (an increasingly common role in the age of self-publishing). Compare the deals you’re offered. Editors with brand-name backgrounds might offer less user-friendly terms (such as hourly rates, which are less predictable than fixed contracts), while less established professionals might offer discounts and extras (such as book formatting and publishing consulting). Don’t be afraid to ask. Hiring an editor is a professional investment. A sample edit will allow you to estimate the value of the service, but never forget about the price.
Regarding your last question, I know of no editor who gives a money-back guarantee for occasional errors that happen to slip through or for a different opinion by a later editor. I’m afraid such things are just the nature of the publishing beast. But by having a shorter portion edited first, you will get a decent feel for whether someone is the right editor for you, and will be able to be confident in his or her work on your entire book.
