You look for a newbie friendly provider, give her the info she needs to screen you, and you meet, you're respectful, you lay down the correct donation where she can see it, and you have fun, leave when you're supposed to.. a very happy boy.
Lots of providers in Austin btw. You should post this thread in Austin and see if you get any nibbles.
As for contact, every provider is different in how she likes to be contacted. Do your homework. Research her, her reviews, her site, etc... always be friendly and laid back. Don't be an ass.
