Time-sensitive. I need to reply to my client today. I've got an offer to write an ebook. My going rate is $25 per hour, most of which is web content I perform on a regular basis for the same client company. E-book client is asking for a project-based fee and I have no clue what to tell them. I've read some people say it's best to go by page, but I'm not sure how many pages 10,000 words converts to. Some say 250, others 450. Even so, I'm not sure about a per page rate. Not sure where to start! Help!
