I looked into using US Foods / Sysco, but they require a min $500-$600/week order. With that, I am using Restaurant Depot and Sams Club for about 85% of my needs.
I am currently working a meat provider who is provind me 100% grass feed, angus beef and kurubuto (sp?) pork for almost the same as I was paying at RD.
Plus, the folks at my market are hung up on the grass feed beef. YMMV
