Where to buy quality whole grains

looking to buy direct... wheat, barley, corn, oats, garbanzo beans, other dried goods. We're planning to buy a grain mill and want to be sure we have a source to buy the grains, pref. directly from the grower. So far, the only who grain we have found is marketed towards hipsters and supremely overpriced.

I like Bob's Red Mill in Milwaukie, OR
