I have had my contractors license for 4 years I really didn't do any work un till lately I bid my first house I really did all right the owner of the house wanted to supply the parts he thought the supplier was his friend but the supplier made it look like he was getting a good deal by selling him every part separately all I did was bid labor but the supplier tried to make it look like I was ripping the owner off telling him I would add alot of money to the parts and anything else he could think up the owner finally seen that I wasn't trying to rip him off but the supplier still tried to mess me up at every turn I wanted a 40 ckt 200 amp panel the supplier sent a 20 ckt panel with 40 thin breakers the panel had no provisions for the extra grounds and neutrals alot of the parts I ordered he sent the most expensive thing he could find and thin made it look like that was what I ordered so the price was hirer than the owner expected I charged $4200 for the labor the house was 2400sq ft I live in new Mexico and the prices are a little bit lower here I fill the bid was fair the question I have is how do you control some nut at the supply house
