Glenn1,
Like you've already been told, the best thing to do is pay the money and get the expert legal advice on which type of a corp would be best for you. I owned a rather large corporation several years back and it was a Sub Chapter S type corp. In that type of a corp, all the profits flow back to you as income, but you still have the protection of the corporate vail.
For me at the time, that was the best way to go. Now, I have a "C" Corp, as that is the best way for me at this point.
It all depends on what you want, and how you want it, as to the best filing for you.
