Young Boats in Inglis does rebuilds. They aren't cheap, but they do great work. If you are familiar with their line of boats, you know they do quality work. I am doing my own rebuild, but I had them gelcoat my hull a few weeks ago. I also get many of my supplies from them, as well as advice.
Also, to your south, Eugene Sun also does good work. He used to be active on this site, but I haven't seen him post recently. I'll look for his number and PM it to you. I used to purchase my supplies from him, but he stopped doing that. He also gave great advice.
