Book Editor

I need a Copy Editor for a humerous non-fiction book that I am writing. The book will be approx 17 - 20,000 words, and I am happy to be quoted per thousand words, or a fix fee. I believe there may be a bit of work to do on the grammar. My deadline is fairly tight, so could all bidders please give me an estimation of when they would be able to complete the work by. I do not mind if bidders have not edited a book, but I do need someone with experience of editing. Thanks
