I have no food service outlets any where near me here in pizza waste land central NC.
You've got plenty of pizzerias in Durham, right? If you've got pizzerias, you've got a distribution network for commercial cheese and flour. I am in no way saying that it will be easy to tap into that as a non commercial entity, but, when there's a will, there's usually a way.
I'm curious, do you own your own business? Do you have a tax code? That will go a long way in dealing with some of these distributors, even if the tax code is for a company that's entirely unrelated food related.
The also the more expensive option of befriending a pizzeria owner. You're a pretty friendly guy, Bob
Is there a pizzeria owner that you could befriend who could buy you some of this stuff? (at a markup, of course).
