Beat Sports Betting

I know nothing about sports betting and i want to find an expert to answer my questions.
Specially someone who is familiar with online sports betting (and the corresponding websites like don best, covers, vegas insider etc…)

I have been looking all over the web for free tips about sports betting but everything I come across costs money or they give you one pick and then you have to pay for the rest. I dont want to pay someone to tell me who to pick then lose more money if that pick is not good. So if anyone can help i would be very happy.
