BME is a communty that has alot of info available. Try this as a start..

I would suggest you ask around, find out if any friends have a similar piercing to what you want and talk to them about any problems. Then ask where they had it done at.
From what I understand keeping the piercing site clean is super important. Also, just prior to going in make sure you shower and douche. They may not say anything right away but I have friends that have horror stories about customers.
Make sure you are comfortable with who you are dealing with and what you are getting.
Good luck!
