Homeboy, try looking at the games or looking for some winners yourself - it is much more satisfying!!
And honestly, if you "need to make some cash quick" gambling probably isn't your best option - Do you live in a hot or cold climate? Maybe cutting lawns or clearing snow from driveways (depending on what type of climate that you're in) would likely be a better idea - with gambling you are just as likely to fall deeper into that hole you seem to be in.
What's the problem is it rent money you need? Do you owe a drug dealer some money? Maybe you can borrow some from friends or family to help you out - gambling with money you can't afford to is really not the right way to go about it and im not trying to be funny I am just giving you some advice.
But anyway if you insist on betting there are lots of people in the forums who give good advice (I'm not going to put a list of names together because I'm surely gonna miss somebody if I do that!!) just have a look around you will spot them - and of course there are the PREGAME PROS who can advise you...
