What country are you in? If you are in the US then there are a lot of feds that are either untested or have untested divisions (usually called "pro" as opposed to the tested "amateur" division). Off the top of my head, RPS, WPC (whatever the US affiliate is), GPC, IPA, IPL, SPF, USPF, USPA.
I live in Canada, in my case I would have to go out of town if I wanted to do an untested meet because the only ones here in Ottawa are an IPF-affiliated fed. To tell you the truth though, I have never seen anyone get tested at a local meet. Now they have a rule that if you set a provincial or national record you get tested, there is supposed to be random testing too plus if you make insane progress in a short time they will go after you. If you are not really above average then there is a very low chance of being tested. You can always refuse and get banned too. Personally, I would look for an untested meet if I was you.
