Ballpark estimate?

by Morgan
(USA)

Hello,

I am interested in self-publishing my book. It's around 50,000 words. Although this book has been rewritten from beginning to end twice since I began it eight or nine years ago, and has been proofread by numerous friends, but I wanted to find a professional editing service to make it more professional before moving forward with self-publishing.

I was thinking of using KickStarter to fund this and other book-related expenses, and I was hoping to get a ballpark estimate so that I know what to set for my goal. I would be willing to provide you with more information if necessary, of course. Prior to accepting anything, I would go for the sample edit; if our styles are compatible, I might even turn to you for the sequels (I have thus far written roughs for seven and a half sequels, as well as a related book of short stories.)

I appreciate the fact that you go case by case, but without a range (even a wide range), it would be very difficult for me to set an appropriate goal. Even a ballpark figure would be helpful; I won't consider it a legally binding figure or anything.

Thank you for your time,
Morgan
