I don't know where you live, but often state schools offer a very reasonable price tag and provide good opportunities where your roots are established.
Regardless of your credit, you will be able to get federal loans of $20,500 per year. During year 2 and 3 of law school, you may qualify for some other federal programs because you will not earn much money while you are in law school. Federal loans are awesome! If you borrow the full amount, you can always lock in a payment below $400 a month and, depending on what type of work you do, even lower. Schools also offer student loans that wouldn't necessarily focus on your credit score.
But, the best financial aid you can qualify for would be a scholarship based on LSAT score. Take a prep course and study your ass off, and you might get to go to law school for free!
In my signature there is a link to a free guide that has a checklist for getting into law school, it may help.
