soda blasting

I need a little advice, seems to be alot here for free. I've got a 71 demon project. I bought a black H code 4-speed a couple of years ago, then i bought 4 or 5 parts cars and I'm ready to get started. I want, I think, to buy a soda blaster and air compressor to start stripping old paint and then epoxy prime the car. I want to learn rust repair and panel replacement but i think i'll let a body shop do the rest. Any way compressor size / tank size etc. and soda blasting equipment from Eastwood or ? Big or little. I might want to offer this service to others, if i'm any good, lol, so it's not for one time use. what do you'll think? just in case, i'm near Houston, tx.
Here's 2 more cents, I'm getting to the assy stage of a 1968 mustang coupe my daughter and I are building for her and if you want to doit yourself and invest time heres what I did. I sand blasted the inner door openings,inner
wheelwells, rear tail light panel, rockers, door edges and any panel that did not have a wide flat area that would warp easily with an offshore pressurized sand blaster. It takes the rust and everything, works great. I have a 3 cyl upright compressor and hooked my portable compressor together with a T connection. All of the flat panels I did with a 4 1/2" angle grinder and a disc they call a scud disc. Thats not the actual name but it escapes me right now. They're made by Norton and removes paint, rust and bondo but doesn't take any metal and is suprisingly fast. Ya we have a few hour into it but the money you spend to have it done($800-1200) you can invest in a compressor, blaster, grinder and I have all the equipment to do my 71 Duster this winter. I found it very satisfying doing it myself. Kev
