The studio looks like it will be awesome dude, congrats on going forward with it. I'm still currently working full time as management at a grocery store and recording/mixing bands as often as I can, but still living at home, working on saving up enough capital to buy some property and build my own house, of course complete with studio space attached (or detatched, who knows). The only thing that worries me about doing recording full time is the lack of health insurance...I don't want to have to sell off half of the studio just because someone got in a car wreck, you know? When I get married, hopefully the wife can have a job that takes care of the insurance end of things!
Worst case, I'll work the grocery store JUST enough to keep the benefits...but I really, really would prefer not to.
