I would go through my nearest chapter of NORML to get a lawyer for any pot related issues. They would be the kind of lawyer that would have alike personal feelings towards your cause and "crime".
I would also feel much more comfortable talking with them about any issues directly related to your work. Find one that has court experience in the nearby areas to where you would most likely get in trouble in.
As far as just getting general information about laws, sentences, specific cases in your area - google is your friend and its free.
