Using an excerpt from your manuscript (in SMF), I'll do a sample edit and provide you with an estimate. I charge $30 per hour and ask for a deposit to save your spot and to cover some of my hours.
The actual price could go up or down, depending on what I find when I edit, but the estimate should give you a general idea for budgeting, and I'll of course communicate any noticeable changes so there won't be any big surprises. Please note that several additional hours are included in the estimate to account for a critique letter.
* The Editorial Freelancers Association offers typical rates in the industry here. Keep in mind that they can still vary widely depending on the project, editor, and what the writer wants.
