Well officer, you just call 1-900-fuc-koff and ask for dr. dontexist. Sorry but your question sounds alot like "hey stoner guys, got any leads on sketchy doctors I can fuck with, maybe get a half legit stack of paper resembling legit paperwork and fuck with a compassion club too?"
but this is where the problem in the state exists...so long as your recommending dr does a viable check up, make documented notes of his findings, you should be good.
I just would not trust any place that gives a cert without any records or physical checkup. If there is an issue, and you wind up in court, the cert will be the only thing holding you to being authorized, thus no good cert, no authoriztion , no defense ability.
fwiw, i dont have insurance either, and its never been a problem, but the needles we and the Dr has to thread are a bitch.
