If you instead decide that self-publication really is the right option for you and your book, this means that you have chosen to serve as both the author and the publisher. That means that you will have to (A) perform yourself, (B) find friends who will perform for free, or (C) hire professionals to perform all the tasks of a traditional publisher, from editing to marketing to distribution, all on top of performing the tasks of the author.
For editors who are charging pennies for what should be hours and hours and hours worth of work: I am saddened that you would ruin the market for those who have the expertise and ability to charge what it’s worth. You see, an author whose book needs a whole lot of help will see your rock-bottom prices and think that’s the norm. But the reality? That’s not normal. It’s not normal to charge sweat shop rates for something that requires top-notch quality.
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 cannot speak for all editors, of course, but I know I and many of us would be open to editing just part of your book at first, say, a particular chapter or two that you sense needs a lot of work. That is often enough to show you mechanical errors that you tend to make repeatedly. You can then go through the entire manuscript yourself looking for as many of the same kind of errors as possible. You will sharpen your basic writing skills in the process, and it will pay off in all future projects.
