Lot to learn. You can only really pick up volume work if you are part of a network. As Mark says worthwhile contacting a few local franchisees such as Rainbow, ChemDry and the private companies such as Munters and Belfor and offering your services as a subby. I know one guy picked some work up in the recent floods and he had never done it before.
I know contractors who have grossed in excess of 1 million pounds this summer.
