How much is business insurance for small business?

It depends on the type of the business and the type of insurance you are interested in, or in need of. As you know - there are many different insurance policies and you should take the time to learn them and to choose the right ones for your business. You should consult an insurance agent or broker, but ensure that he or she is duly licensed in your state and that the insurance company that you are placed with is authorized to transact business in your state. The latter two confirmations can be done by consulting or calling the state Department of Insurance.
