I can't give you any recommendations for brand but I do have a tip for you. We had a paint crew where I worked and they did thousands of square feet of epoxy floors and they always wore old golf shoes when they were putting the epoxy down. You can walk across wet epoxy and it fills back in where the cleats were.
It's been a while but as I recall they mixed the hardener in the 5 gallon buckets that the epoxy base came in and dumped it on the floor and squeegeed it around. They could cover a lot of area fast and it was always so nice to go from a crappy old concrete floor to a new epoxy one.
They also had a machine that shot steel balls at the concrete and caught them to rough up the surface so the epoxy would stick better.
