Need Professional Book Editing Services – Any Advice?

[LunaDaisy]

I’ve finished my first book draft, but I know it needs a lot of polishing. I’ve heard that professional book editing services can make a huge difference, but I have no idea how to find the right one.

What should I look for in an editor? Should I go for a full developmental edit, or is a copyedit enough? Any recommendations for affordable yet quality editing services?
