Good body shop? Atlanta, GA

Wow, great responses! Thank you all so much.

Brief Situation: It is a 1964 Valiant convertible that runs and drives great. I removed the front seat to do some cleaning, and when I stood on the floor pan towards the rear, it "collapsed" a little bit, but sort of "sprung back when I got off of it. I haven't even pulled the carpet yet but will in a couple days.The body looks to be in decent shape, so I don't know how much work it actually would need, other than a basic sanding, and respray.

I was contemplating asking about a rhino-liner type underspray to make it bullet proof in the future. I don't know if anyone has done this or if it would even work, or if it is even practical. I want it to be a solid daily driver, so I'm not trying to "restore", just to make it real durable and tough.

IF it needs a rear floor pan and a small hole filled in the trunk, along with basic panel alignment, new underseal, and engine removal for proper bay spraying how much would be a ballpark cost estimate? My initial guess was $3000, but I have no idea if I'm even close. I'm not looking for solid figures, just trying to get an idea of what I'm getting myself into.
