I'm not sure, the real problem is the exchange of goods and money. I'd either have to come up with enough of my own to front it until I could get it down to you for the payoff, of you'd have to send me some (probably not the best idea over the internets).
After that it's easy, I give the list of parts to my boss, he uses his wholesale account to buy them, they get delivered and there's generally a small shipping fee, $12 or somesuch, then I pay him, I can do with the parts what I want, which would mean driving down to the Napa Valley and exchanging them with you for money assuming I fronted.
