There are a couple of problems with horizontal compressors on wheels,
big ones like you want are top heavy, so a wide base will be essential.
They are also heavy, so normal wheels won't hold up long.
If you were close, I'd make you a deal. I have a monster 5hp 240v
compressor on wheels, sort of, I lost interest in the project and moved
on to vertical compressors, I've stripped a few plumbing pieces off of
it, but it used to be my main unit & would power impacts & roofing
I bought a pair of 1" axle roller bearing solid wheels, like on rail
road carts for the heavy end, but never got around to putting it all
