My comment was going to be: if you really haven't got more than $20 are you sure you want to risk it gambling? I'm not convinced being staked will be good for you (or your friend) but yes, you are now adequately rolled for $10NL. Next time, take $50 and play microstakes - but if you can't even afford that, seriously consider your approach to risk and whether it's compatible with playing for real money.
