Workers compensation typically adds 2 - 4 dollars + to an hourly salary while health benefits depending on the plan typically add 2 - 6 dollars on top of the hourly salary. Most plans range from 1000 - 2500 a month depending on the level of coverage (accounting for the fact that typically the employee pays for 50% + of the monthly premium out of their base salary). General liability insurance is a collective rate for the business again the rate varying based on how much coverage they opt for.

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.
