WTB - Cordura 500d fabric

I'm looking to make my own backpack so I can create a design specifically for my body. I've tried various packs and each one of them just seems to lack one thing or another so I thought I'd take a leap and make my own. I'm looking for some Cordura 500D - black fabric to use on the back panel. If any of the DIYers out there have any left over from your creations I'd love to buy it off you please.
Happy Hiking!!!
