How much will it cost?

My rate is $50 (USD) per hour, and the total cost will depend on the size and quality of the document.

Note that you can try my service without paying anything. After receiving your manuscript (sent to me by e-mail attachment), I will spend 30 minutes editing the Introduction and then return the manuscript with comments and also tell you the cost for editing the entire document. You can then decide whether to hire me. If you decide not to hire me, you will not be charged for the 30 minutes. If you decide to hire me, I charge $50(USD)/hour, and a 20-page, double-spaced manuscript might require 2 to 7 hours, depending on its condition. Again, we will agree on the total charge ahead of time.
