As a ghostwriter, the amount of pages or words do not matter to me. The genre in which you want your book to be is somewhat of a different story. I can write just about anything besides research topics. I can write a book that involves research but it depends on the topic so anything medical or involving the law I will not be a good fit. For pay, I would like $15 an hour and for a non-hourly wage, we can talk about that when we talk about the job details.
