As for editing, it's a good idea to price necessary services so that you'll know how to set your budget. There's a lot of variation online. For reference, my base price is $500 for books; for shorter works there are other options (http://penultimateproductions.weebly.com/pricing.html). If you look around, you can find other freelance editors with prices posted, and see who seems promising for your project.
Cool!
