I do developmental editing mostly, so I charge a flat rate to read once and build an action plan, half before and half afterwards. Then we contract to work through the plan, where the bulk of the editing takes place and for this I charge 25% up front, 50% after the developmental edit, and 25% on completion of the final proof. I find that authors appreciate the spread payments and the transparency this brings.
There may be provision to have a call to discuss the work, or it may purely be the delivery of a structural report or a line edit or proofread manuscript. I've worked with professional editors for the last ten years and have never had a call to discuss, but if you're the type of person who wants that, then make sure you put that into the contract upfront along with anything else you are concerned about.
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.
– Many self-publishers need less specialization. I sought an editor — mostly a copy editor, but also this is the only person who could tell me if I ramble in a particular chapter. I couldn’t afford a full dev edit, but I think I’m typical in wanting an editor who will tell me what my friends wouldn’t, and maybe switch hats for small sections where it’s needed.
Well, hopefully, now self published authors can now see that there are a lot of AMAZING editors who can do outstanding work for a LOT cheaper than that list. As for the free editing sample, yeah – so long as the editor has solid proof that they are a legit editor with great credentials, that’s all you need. But if they don’t have that and won’t provide a free sample edit, then there are a lot of fish in the sea and it’s best to move on.
A site where you can hire editors on a freelance basis. Has a range of prices so there is something to suit most budgets. Be sure to take the usual caution when working with a freelancer. Check out their reputation carefully first and communicate carefully with them in order to determine a schedule, payment expectations, methods of communication etc.
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.
