Another place to find professional editing service is the team at Ebook Launch. They have a team of professional editors who can polish your book for an affordable price. You can even get a free sample edit of 750 words to help you decide if they're a good fit. The small team at Ebook Launch also provides amazing book cover designs and formatting in addition to their editing service.
I’m not sure why you said “ha” after Fiverr. I’ve been a proofreader (more like a line editor/copy editor, really) for 3.5 years and have worked on many book projects there and outside of Fiverr. (writerkerrie) … Yes, some editors on there are crap and I agree, but many of us ROCK! I only charge $5 for 1,500 words of text (I only receive $4) because I LOVE WHAT I DO and I love working from home and being able to homeschool my kids. I am also an author myself and want to help other authors by not overcharging them. I have received MANY book projects from authors who paid the rates you describe above and I ended up finding DOZENS more mistakes and GLARING errors that for $70/hour … well, they should have been caught. Please don’t write off Fiverr. Some of us care about what we do and we do it well and you can tell from my almost-1,600 great reviews that this is true. Don’t hire someone if their gig is written poorly and they barely have any reviews!
