Would a business that has something to do with steel or welding be good in Southern California? My father is looking start a business in one of the Sun Belt states when he retires, he is a top foreman in the New York City Ironworkers so he knows a lot about steel/welding and things along those lines, hes looking start a business in a place like Southern California or Florida and one here in NYC. What type of businesses are in demand in Southern California?
