Most of the startups I've participated in have been more on the scale of what you're describing here (FWIW, I like these kinds of challenges more than something that is "just" software in the cloud, but to each his own). I'm more of the business-guy than the hacker guy, but I've been known to make a double-sided PCB layout, toss on and program some PIC chips and create a server-backend when need-be. Anyway, if you want to discuss your idea offline/non-public I'd be happy to offer some free advice (it's worth what you pay for it) and maybe point you in the right direction or give you some idea as to how to proceed to bring it all together.
