As this is a rakeback free discussion zone, the only advice I would say is go to the Classifieds and check out some of the sites (
www.rakerebatereview.com is a good one to start at). Write emails to the people that offer the rakebacks and ask them as many questions as you can. They will be more than happy to answer them to try to get your business. You can pm me to ask about any personal experience with it... and no, I am not a rakeback offerer. But i was in the same boat as you 3 months ago.
