I had a phone call from a company who fabricates steel for Jimmy Johns sandwich shop today. They left a message asking me if I would hang some steel for a location about two hours away. I've done this type of work, but its been 10 years since I have done this type of job. I've never done this for myself as a business, but I'm seriously considering bidding on this job. I know that I would have to rent a lift of some sorts. Most of these buildings are small so it would not take long to assemble. I only want to hang the steel and nothing else. Anyone know how to bid this sort of job? Do you bid it by the square foot?
