I would start by asking the owner of the wire how much they want for it. With that much weight, they might be getting a higher price than joe shmoe off the street. But usually, they would want equal to the scrap yard or more cause they can always sell it to the yard if you dont make a higher bid. Or they can have a contract with the scrapyard. I never bought wire, but you got to know what the market is doing and now its in a downward trend. but who knows, you can try it and see what happens. there's only 1 way to find out
