You may want to hold off a bit before you start attempting to trade. Get yourself some solid training about the business, save up some money, and then take the leap.
Some firms will let you get started with $10K, but it is ill advised in my opinion. It is just too much pressure to make money....sort of like playing in a $10 Minimum poker game with $100, you can only make a few bets, and the "ante" (costs) will eat you up.
Take a step back and be objective about the whole thing....come in when you are ready...IMO
