Paying for editorial services

If you look in the Publishing Resources room you'll find a few recommendations, but much depends on your genre and how you want to proceed.

I'd also say you largely get what you pay for, so don't cheap out. Be prepared to pay professional rates

I don't know if it's too late, but I found my editor(a few actually, which a I contacted, and decided on one, but all were great) from a list on Joanna Penn's website, TheCreativePenn.com, under the resources for authors page. She has vetted them all, but like anything, you should interview and use careful judgement before signing any contract with anyone. I was very satisfied with the woman I chose for copy editing of my first novel and actually holding on to another for developmental editing on my second novel.
