I dont know if you have knowladge about affiliate marketing. That is what i do. But you need to made yr mind first. You have to spend atleast 3 HRS per day, for the first couple of months.
Im a member of clickbank pirate. you dont need a website. but you have to adverstise hard. by any means, blog, chat, tweets, facebook, forum, articles etc. so its sounds quite hard but after 2 to 3 months you are right there.
