I started out with the same amount and played SnGs, and built it up to $650 in around 3 months of occasional play, but if I could go back and I would start at .01/.02NL full ring. SnGs really kinda suck and it's much more fun to play ring and you learn so much more. It's a slow grind, but if you follow spoons BR bonus/rakeback plan you should be a very good player eventually.
