I used to work at a company that did incorporations so I may simply be parroting the company sales pitch here, but I did get the honest impression that finding a company that helps you incorporate can really save you some huge headaches later on. The state where you incorporate can have a huge impact on a number of things and a company that specializes in this can steer you clear of some minefields. It will cost more but I think it's very likely to be worth it.
