If you are comfortable doing it yourself you can get everything you need at Garage Floor Paint | Concrete Epoxy Coatings | Epoxy Coating Kits. I just did my garage, golf cart garage, and lanai for under $600. I have used this before at home up north and it works great.
If not, call Jose Gomez 352-348-6957. Best painter I have ever used.

I used Edison ConCreations Inc. 352-406-8775
