There really isn't a straight answer to this. I can tell you the typical is $0.25-$1.50/page rate for ebooks. I see some 100~ page ebooks from past affiliates that go for 50cents/page, but then some diet book sneaks in at $1.25/pg with 40 pages. Its really not quantity! This is a market of quality. Just look through clickbank's affiliates for ideas for crap landing pages and crap ebooks (for the most part, spare maybe ~10). Good sample pages, good outline, no boring plain black and white text, and connect with what your clients really need. Create a wiki/forum or something for registered users to access. The book isn't the only part... you want to build a community (elo adsense!)
