I have a friend of mine who is very good at sport betting, he has already a big fan page group where he posts his tips for people and most of times he and his fans group wins. He already earns money (not much but good cash %) as affiliate with betting websites giving real winning tips to people.. He knows I'm into Internet Marketing and he asked me how he can make more money with his betting tips that gives to people and he would split money with me with new earnings. I thought various ways to monetize his betting group, I could build a list of his fan then promote some good product related to betting, like a clickbank product or betting software something like this.. Do you have any experience in this field, which are best ways to earn money with betting products? I'd prefer whitehat ways because he's got a large list of people who trust him, so we can make good money only if we offer something very valuable, thank you guys.
