I totally recommend US Foods or Sysco for suppliers of high end products. The problem with them and most other companies that deliver food is, the minimum delivery amount. Most companies require at least $450.00 minimum order to be delivered. If you are only ordering a few cases of food per week, they may not an option for you.
I do not know where your store is in Georga, but there is a company there called "Restaurant Depot". The RD will not have the selection that US Foods or Sysco carries, and in some cases, the quality is not comparable either. The food quality will be above the Sams Club, as well as the prices.
One thing the Restaurant Depot excels at is paper prices. You may save quite a bit of money each month buying napkins, hand towels, paper cups and lids.
If you have a Sysco or US Foods house near you, one last option may be will-call. You call in your order and go pick it up when it's ready. If you try this option, remember to take a calculator with you, because I have had large fluctuations in prices over the years.
Keep us informed about what you find, it could help other independents make more informed decisions.
