if I were you I would check the signatures of people posting in your thread,there is pretty much every major betting site represented
then I'd go to games and rounds and look if there are any free giveaways or bonuses to get you started
usually dice sites like the one in my signature have a free faucet to test the game
but I know players who were able to make good money starting from scratch i.e. from a free faucet
and the main thing about gambling-stay in control
never ever gamble money you can't afford to lose,even if you are 100% sure you will win
