Reilly Bodycomb (Remix Dojo) is a master at leg locks. Its a great place to train lower body grappling.
There are probably a lot of options for you. However unless you are very athletic with a promising competition future, don't expect any instructors to take any real interest in you. Best thing to do is scrap money together and get a job. Get a credit card and charge your training on that if you are that serious.
Otherwise scour the city for judo programs/college programs that allow you to train.
Also for the lurkers and others who post about looking for a gym. GUYS IF YOU ARE SERIOUS ABOUT TRAINING THEN JUST GET TO IT ALREADY. Its a lot of B.S. to be "looking for months" to find a place to train. Time is wsating, you are not getting any younger.
