Also, An airbrush will make (in my opinion) the single biggest improvement in your game. It doesn't have to be an expensive one... I have an old Paasche single-action that I've used forever. The compressor is an investment, but a real airbrush compressor (with a tank, regulator and moisture trap) is quiet and pleasant to use.
One of my side hobbies is trying to get good finishes with craft paints, like Delta Ceramcoat. It's a little more work, but it's possible. Real model paint usually gives a nicer finish, though.
I'm in GA also, it's a shame that there aren't any real hobby shops here- at least not in coastal GA. I used to love going to a good hobby shop!
Have fun!
