A late dilemma in this process... One of the things I learned researching self-publication is that the author should always get professional copy-editing for the book. So, I budgeted that in (at about $2.50 / page, which is what my research showed it cost).
However, reality is sinking in. I looked at a professional editors site for Colorado. Of the 16 (or so) people I have contacted, most of them were too busy to even consider more work. Of those that would consider it, three have supplied a sample edit. Unfortunately, two of them went way too far and the third did not go far enough. I want a copy-edit, not a deep dive and 6 comments in an entire chapter isn't really worth the $1100 (or so) I would have to pay. Ugh!
Since the package I am planning to get from Wasteland Press includes 20 hours of copy editing (that they admit isn't really enough), I am considering using them as my final editing. I would like to find the right level of editor out there, but it doesn't appear to be happening and so far my daughter has proven to be a superb editor (good thing that is going to be her career).
