I am not even sure you will find a compressor big enough at home depot. Seems like what they call a 5 hp has a motor about the size of a household clothes dryer, and the results to match. I drilled out the passage in my sandblast gun to allow more flow mind you, and get the results of a commercial sandblaster out of it.
As to air supply; I have an older 2 hp (with one of those massive old style 70 pound electric motors) and will run one of those wheelbarrow type gas compressors in tandem with it when I sandblast. I am using one of the princess auto made gas powered compressors, somewhere around the 9 horsepower range. It will also keep up enough air to use a commercial spray gun. Once I get electricity into my new shop, I will hook up my 2 stage 7-1/2 horsepower compressor, which I got from a auto dealership closeout.
I will echo Lynn's recommendation to avoid that dust. I'll snap a photo of my exhaust system when I get out to the shop later. It is the best $120 you will spend, as it removes all dust from the cabinet, dumping it outside.
