Thanks for your input, but as caroliprowash said, you cant hook up to the city system without getting a thousand dollar fine or ticket. Contractors will not go for a tank of water costing as much as some of the houses. Also, with a purchase order system, your prices are entered into the system and spec'ed out for each job, so they do know your prices. You know what you will be paid before the houses are built at the time the permit to build is obtained and a PO is issued to you. So taking the total cost of the job and saying 165.00 more per house on top of that, its not gonna happen. You will price yourself out of business and you are in business to keep business.

FCPWLLC you said, "move on to the next PAYING customer". Well you just dont do that when "that paying customer" alone is putting 40 grand in your pocket a year. He is more than "just another paying customer" to me.
