My goal is to keep your costs down while making enough to justify my time. It’s a very rare self-published book that will sell enough copies to pay back a $1000 editing fee. At $.01 (1¢) per word that many copy editors charge, a 100,000 novel would cost $1000 for fewer services than I include in your edit. One popular editor charges that for just “grammar, punctuation, spelling”. And it’s probably worth it, but more than most part-time writers can afford.
Yes, I could charge that much, but I have to live with myself afterwards. I’m retired and just looking for a few extra bucks to supplement my Social Security and retirement income.
If your 100,000 word book is almost perfect, I can get through it fairly rapidly and keep your costs fairly low.
If your 100,000 word book is “average”, it’s going to cost a bit more.
If your book needs a lot of corrections (grammar, word choice, reconstructed sentences, rewritten sections, etc.), it’s going to run well over $600. At this point, I’m likely to recommend that you do some more work before spending money on an editor. But if you want me to fix it anyway, I’m more than happy to bank your money — as long as you go into it with your eyes open.
