I did my own, so I cannot recommend someone to do this work, however I have few words of caution. First make sure whatever is used will stand up to automotive and golf cart fluids (gasoline, oil, brake fluid and battery acid to name a few. Second the garage floor will get wet, make sure you get a friction additive on the final coat (like shark grip) or you may end up with a very slippery surface.
I made the mistake in the first case the Xylene based clear coat sealant does not like gasoline, but I did add shark grip so at least I do not have the slippery surface.
