This sounds like a great field to have a business in! The problem, however, I think is that many business owners are going to want references and want for someone to be bonded before you can win the contract for the jobs. You will also need to have commercial equipment which I think can be costly?
This is a business that I would love to get into. It seems if you can take care of those things on the checklist that I referenced, you should be able to have a thriving business with all the new construction in the building of new small retail office space and new housing construction.
