Find out if any of the law schools you've applied to have sponsoring firms and apply for those scholarships. Sponsoring firms will usually award you with half of a year's tuition money, on the condition that you work for them the summer after your first or second year. You would need two of these scholarships to study free, which is possible if you speak to the law firms directly and perhaps offer to work longer for them.
Approach local law firms that aren't sponsoring scholarships at any local law schools and ask them if they'd be interested in sponsoring part or all of your tuition. You'll have to provide them with a copy of your resume, transcripts, LSAT scores and you'll have to offer to work for them during your summers off or longer in order for them to consider it.
Talk to the professors at a local public law school and ask if you can audit their classes. While most law schools may not allow you to watch class for free more than once, a given professor may not mind if you provide an explanation.
