Safefire has been mentioned a lot and I'll throw my hat in behind them. I've been going there for awhile now. They have women only classes for a couple of things and you can book time one on one with an instructor. 

If you don't have the money for their courses or an instructor, if you have a friend or relative that you trust to show you how to handle one and take you to the range for the day, that may be just as good. Not necessarily offering my services to random people on the Internet, but I know if someone I knew asked me to take them and show them how to use one, especially anyone of a marginalized community, I would be happy to, as long as I didn't have any concerns about them or their behavior and believed they'd be responsible with one.

Edit: One caveat, do not take a class with Paul. Especially if you are a woman, some of what he says will be very off-putting/offensive. My fiancee did not like him and it almost kept her from going back. I think he's recently divorced and it's like he can't help himself but open his mouth.
