Work in house first. That’s the best way to learn all you can about editing and proofreading and make good connections. I have met several people I’ve worked with from hanging out in Twitter and responding to tweets asking for an editor or proofreader, but I have had the most success from business connections I made while working in in house. Other things – a web site, professional associations such as the SFEP and the EFA (though I can’t say much more on these as I am not a member of either yet!), social media.
This is great advice, Val! Thank you for sharing. I’m a freelance editor as well. I agree with the advice about giving a newbie a shot because I was a newbie freelancer four years ago, with newbie rates because of being a newbie. But I had already been editing for five years in-house and at professional competence level, so my early clients got a bit of a bargain from me!
The quotes I posted are for a specialized genre – romance. These books are shorter than many other types of fiction and yes the editors are professional. Many do this as a favor to authors they love and work with in publishing houses…so they lower their rates for private work. Over time of course, their rates increase but the prices I quoted for my industry only.
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.
Use the Library of Congress database to find publication information. The Library of Congress is the national library of the United States, and has one of the largest databases of books in the world. Go to https://www.loc.gov/ and click the search bar. Type in the name of the book and the author’s name if you have it. Scroll through the results until you see the version of a book that you’re looking for. Click the title to open the book’s informational page and look for the editor.
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.
