Looking for a few good nuts

You would think, since I have a cousin who owns a walnut orchard getting a hold of a few nuts in the shell wouldn't be so hard. I'm working on a new project for a class (yes, it has something to do with paper crafting) and I can't for the life of me find big walnuts in the shell. Since I've been on this diet, walnuts are my new potato chips so I have tons of shelled nuts around the house. Anyone out there have to good source for local "in the shell" walnuts?
