If you currently need an editor, I would be delighted to assist you. I've been a copy editor for over 10 years. At present, most of my clients are independent authors, but I would be delighted to work with an English-language book publisher, as well. To date, several of the books I've edited have been published as e-books, and one as a print book. Some of my references can be seen on thumbtack.com. I can provide copyediting, as well as developmental editing, at the minimum rate of $45 per work hour. You would receive a firm estimate of cost, work hours, and delivery date(s) for your approval prior to my starting work. I would also be happy to provide a sample edit of up to 1,000 words.
Acceptance of your assignment would be conditional upon seeing the entire manuscript before confirming my acceptance of an editing assignment, or sending the author/publisher a firm estimate of the total cost based on anticipated work hours (which would also include the anticipated delivery date(s) of the complete text).
I hope to have the pleasure of working with you!
