On another answer, someone suggested if you want to sell your own ebook, to get your own domain name, get your own site and get an affiliate program, presumably to sell other ebooks. Which affiliate program would really drive sales? Thanks.
You got three networks to choose from.
1.www.clickbank.com Probably the largest market place for download products like books and software’s.
2.www.click2sell.com It has emerged as an alternative to clickbank in the recent times.
3.www.paydotcom.com is also emerged as an alternative to clickbank on the arena of selling digital products.
Ofcourse, you need to get a domain name, site and a great sales page. If you don’t have a great sales page, regardless of the network you are in, driving sales could be a tough work.
All the best 
I use clickbank, but i get better results when I market my products myself. You should learn the basics of internet marketing and try to promote it yourself.

clickbank is probably your best choice ( i am not going to post any links because every time I do I get a crappy email about yahoo guidelines) so if you search google for click bank affiliate you will find them

Clickbank is good, but my biggest issue with them is refunds. CB will give refunds to customers with NO questions asked. I have sold ebooks on their for years and I have had customers email me thanking me for a great product. Then they send an email to CB and CB automatically gives them back their money. If you know how to do it – you can get every product CB markets for free. That is why I moved to paydotcom.
If you are looking to make a living out of this you got to check out the site below. Dude has put up proof he makes $200k per year and is taking in new students
