Belly Button piercing??

Hey! I'm thinking about my getting my Belly Button pierced and I was wondering if anyone has any suggestions. I'm in the Little Rock Arkansas area so who should I go to, what are the prices, and how long would it take to heal?

Also on a scale from 1 to 10 how much does it hurt, 1 being a bee or wasp sting and 10 being someone slowly stabbing you with a large knife.

I am also curious if it's easy to hide them, my Mom is super conservative and if she found out she would probably tie me up and try to exorcise me (yes that is a hairspray reference). Like is it ok to take them out for a little while?

I know some of these seem like stupid questions, but I don't want to just jump into getting one without being well prepared. Thank ya'll so much for your help!!!!
