You don't necessarily have to incorporate (INC) in the US. You can persue a Limited Liability Corporation (LLC), which is much less expensive. But it is state-bound, meaning that if you move from state to state, you have to re-register your LLC in the new state you move, but it is less expensive than incorporating, and a little bit more flexible.

In terms of broadband Internet access (cable, DSL, radio/wireless, ISDN, and satellite), it is much cheaper in the US, with price ranges between $50.00US - $300.00US per month. Cost of living varies considerably in the US, which is difficult to provide advise based on your unknown desirable living costs.
