I gave a customer a price to hook up her generator and transfer switch. She wants to go with my price, but asked me if I could supply her with the material list. I told her that my estimate was free and that if she found a better price then she should go with that. I also told her that I didn't fell comfortable giving her the list because of the possibility of someone else getting the work. She assured me that wouldn't happen. I gave her a deal, and I know that she wants me to do the work because of that (2 previous quotes). Should I stick with my guns and not furnish a material list? Actually, I quoted her from a similar job, and I don't really feel like calling around etc to furnish her with a list.
