How to start a baking co-op? Need advice and guidance!

Hi all,

I need some help in determining the advantages of starting a cooperative for bakers.  Believe it or not, I live in the 5th largest city in the USA and there are NO decent baking supply stores here.  The only one that really comes close is Shar's and she sells grain mills and whole wheats to grind your own.  I'm not really interested in that yet.. and really, I'm just looking for a good source of flours and other baking ingredients that I don't have to buy in 50 lb bags.

Has anyone here ever started one and if so, what was your experience and overall guidelines for resources in how to start one.  Just some thoughts or ideas from the more experienced would be most welcome!
