I would haul it down to the local Grainger, Kragens or somewhere where there're mechanics behind the counter. Bring your hose and a/b as well. Usually that's the kind of thing those guys enjoy, as opposed to selling lightbulbs all day.
One significant caveat with commercial air compressors. They are usually noisy. It's a serious problem for hobby use, because you usually are working after dinner, while the neighbors are home or the kids are in bed etc. So I would seriously consider whether you can deal with the noise. iIf it's quiet, great!
