Hey I think the best bet is to reach out to some people in the gourmet coffee bean space who are trustworthy. Like some coffee-roasters who you've been buying from for years who have dealt with farm-to-table approach. With some vetting you can probably get some worthy deal going.

Off the top of my head I can think of a couple of places in New York that I believe are ran by diligent people. I could probably point you to their direction if that's of interest, but I am in no way affiliated nor interested in getting into that kind of business, just would love to see such a resource not go to waste.
