I am assuming you would like to trade from an office. Have you tried googling it? My best guess would be Assent, they are everywhere. You can trade with or without series 7.
Just moved from Orlando, and can say that there are no trading offices that I had ever heard of. I was there for quite a while, but I could have missed something. Doubt it though.
Its seems most prop firms just have offices in NYC with few excpetions e.g. Bright has an office in Miami and Assent has offices just about everywhere.
I was contacted about this firm (www.scottrends.com) that recently opened in Orlando. There training is with T3live.com and trades thru JC Trading. $7500 total deposit. 5k capital deposit. 2.5k training fee. $150-$250 desk & software fees per month, I can't remember right now to be exact.
