If they had something like "lawgrades", that would be a great starting point! A quick check shows that the don't have such a site. Of course, I'd have to be free from detention to utilize such a source if it did exist. Pretty sure they don't provide laptops in jail.

Probably the best advice would be to contact a family member or trusted friend "on the outside" and ask them to find a lawyer for you, rather than trying to find one yourself.

Goofy's suggestion might be a good one - ask someone that's in the field but not likely to be competing for your services who they would recommend. If you want a strategy, you might ask your friend/family to do a quick google search for the single largest law firm in the area that has a white collar criminal defense practice. Call up the partner who's the head of that practice - you'll get their secretary. Let that secretary (very nicely!) know that you're looking for a referral for a (presumably) non-white-collar criminal defense attorney and ask if the partner has any recommendations. The partner probably has a colleague that they like to refer their clients to, and that person will probably be pretty decent. And the partner will probably be happy to give that referral to you.
