I usually ask for a 10-20 page sample – one page is a bit scant for a really accurate estimate. I’ll do an editing sample, too, but how long I’m willing to make it depends on the proposed length of the piece I’ll be editing. As for the “hidden message” strategy, if I saw something like that, I’d suspect the prospective client was fearful and suspicious and I’d probably run the other way. I willingly provide testimonials, references, and links to published work, so tricks aren’t necessary. It’s important to me to build a professional relationship of mutual trust with my clients, backed up, of course, by a contract that protects us both. I don’t think I’d like to work with a client who plays “gotcha!” Lots of good suggestions in this article, though.
Stephen, you’re right, and I think much of the confusion about editing and its pricing stems from the fact that editors offer a range of services (in addition to a range of experience). It might be best to view editing on a spectrum from broad (developmental) to detailed (copyediting and proofreading). And it’s always best to have as clear an idea as you can about the kind of editing you believe you need.
2. Copyeditors aren’t the last line of defense when it comes to a book’s mistakes. Formatting, which is done after an editor has done their job, can lead to unintended errors being introduced into the text. That’s why it’s important to hire proofreaders to comb through edited text *after* the book has been formatted for print or digital. Proofreaders are your last line of defense—but they’re human too.
