I wanted to know how easy or hard it would be to simply call the people that have received contracts and just tell them about my affordable construction materials, is there any specific point in the contract chain that I should call? I see that they sometimes have these sheets with the list of materials and there prices, if I am simply cheaper or same as the contract states, then can I just call them and offer mine?

Do they always have suppliers on the ready every time for everything?
