I had to take it my belly button piercing out prior to an allergic Reaction to the ring I had in. How long will it take till I can get re pierced?

Wait till it looks healed enough. There are plastic belly rings out there too. A nice place to get them is from bodycandy.com. Be sure to read about them before you get them

My problem is finding a good professional piercer. And is that a really good site to get rings from?
