I was asked by a builder to give a price list on a perticular house for the electrical system without even any prints. He had just given me a list of general appliances no specs on them and listed how many lights and fans and GFCIs and so forth were in this peticular house, and then he wanted me to break them down and price all these things out individually. I'm just starting out so I don't know if this is common or not but it seems pretty shotty, but I don't want to turn him away. My question is would it be bad to do this for him, and have you had to this before?
