Thanks for asking!
I charge $60/hour.
How much time it takes to work on each piece depends on good the writer is to begin with, how good they are at acting on feedback, and how difficult the piece itself is.
Most 800–1,500 word essays go through two edits and a final tweak.
A good way to test the waters is to buy an hour of my time and see how far we get. You may or may not decide to continue with me (most do) but if you don’t you’ll learn something.
