First, you need about 40 crapped-out computers. Hook 'em together for a network renderer (or just take the CPUs out and try to stick them in your existing computer). Ideally, you'd get a more advanced program than Carrara (which is really more entry-level... Lightwave, MAX, and Maya are the big three after proprietary software, but their price tags range respectively from too much to more than your car to more than your car, your house, your neighbor's house, and Switzerland combined). Location is a bit of an issue, but not too big of one. Basically, get the equipment and whatever friends you have who are into CG and the like- and some kinda basic job- and more will come as you work.
