Business insurance and Workers Compensation are two completely different things.
In any case, nobody can answer your question here.
In both cases the premium will depend on where you are and what kind of business are you trying to insure, how many employees you have and quite a few other things.
Call an insurance agent in your town for advice. Independent insurance broker will shop around for you to get you the best deal. Well, the best deal for him, depending on which insurance company will pay him the largest commission, but that's another story.
