Wouldn't "media blasting" be sandblasting?
Nope

Media blasting means I can shoot almost any blast media at something. Walnut shells (don't do a good job), coal slag, glass (gives the best finish IMO), aluminum oxide, etc.
Information alert!
Blasting sand really isn't sand, it's something else. Beach or play sand is made mostly of silica and when fragmented gets airborne really easily. Once inhaled, it'll never come out of your lungs and causes Silicosis.
I'm in Atlanta, GA. I'd have to come up with prices for arcade stuff as I've not done any yet, just car parts. Like I said, the first bunch of unique items will get VERY special pricing as they'll be the guinea pigs and will help me baseline my product costs and times.
As the old saying goes, I do things any two of these three ways:
cheap, fast, good

I know it'll be asked, so here's some more information:
I get powder from a couple of different sources:
