The sponsor manufactures parts for defense contractors like Boeing and Lockheed. The customers have already been charged for the stock so the scraps are not worth much to them.

If you don't expect to come close to the budget limit, just use the McMaster pricing and have $300 in wheel material.
If you do think you'll come close, call up a local vendor and ask for the price of 2 or 3 feet of 7075 in whatever the smallest cross section is that will fit your wheel and account for it that way. Sometimes this might not be cheaper though, as many places will charge you for a full 12' bar if they have to cut 2 or 3 feet off it, as they can't sell it after that.
