Aliphatic Paints $$$$$ Ultra Bright? Paint Shops?

Hi Folks,
Looking ahead, still thinking how to finish the trailer. Paint is still a possibility.
Facts: All told, the trailer is approx 200 sq ft to cover, regardless of what you cover with (its a 5x10x4)
Aliphatic 255 paint (epoxy urethane) is $87 (!) a gallon--I would need about 3 1/2-4 gallons
I some people have referred to a paint called Ultra Bright (? or something like that) which I am not familiar with and would like to get more info about. If anyone could tell me where to go to find that I would appreciate that.
Some people have had auto body paint shops do their trailers--I would like to hear their advice and info about costs with that...
Thanks,
Jim
