You can also check out Fiverr for freelance editors. I decided to submit my first two chapters ($100 for 10,000 words) as a trial. Turnaround is approximately 10 days. I'll let you know how it turns out. There are multiple editors on the site with different levels of experience, although not all edit fiction.
In surfing around for editor prices, I found that a comprehensive line edit will cost about $0.02 per word, or $2K for a 100K book. The price is higher or lower depending on the type of editing you need (developmental editing, line editing, or copy editing). Be careful about the definitions of these terms. Line editing is sometimes referred to as copy editing on some sites I visited.
