I've never had any dealings with a criminal lawyer but I know someone who is a DWI lawyer. He or his office (which is actually in Clear Lake but used to be downtown) could refer you to a good one. I'd trust his recommendations

Look for Pro Bono ones. You may have to call allot and ask but they do work for free it's a charitable deduction for them. If your a woman who's on public assistance or welfare there are TONS of lawyers who will help you for free.
