i was basically 1 step away from opening a shop here or in roa/salem last year at this time - had 2 backers both ready to sign and committed to some good funds. 1 backed out and then i decided i didnt want to bother w/ the hassle of this area......seems like what you think would do good around her fails and what you think will fail ends up flurishing.
I'd be skeptical of a 4 wheel dyno simply b/c of the costs involved, and i know sean at united muff in radford has been talking about a 10+ bay shop w/ a 4 wheel dyno for some time now but havent heard squat on that in about 4-5 months now or more.
Best of luck in all you choose/do bro!
