Hello there! I don't know how long each of the chapters are, but I have experience proofreading and editing articles. I can provide you a couple of Word documents that can serve as samples to show you my work. It is a 1,000 word sample and it includes the changes I made to the original document.
I would like more information about the project, and that way we can negotiate the terms of the bid and the amount of time it will take me to complete the job. I look forward to hearing from you, have a nice day!
