There was a thread awhile back with a lot of info concerning specifics on importing coffee beans. Maybe rose can help find it?
I know you like coffee, but enjoying a cup is a far cry from developing a working knowledge about identifying and procuring quality green bean.
You also need connections to sell those beans once they manage to clear customs. And then there is the logistics of storing bags of beans weighing over 130 lbs. each. Economy of scale means one generally pays less per pound for shipping larger quantities of a product than smaller loads. You will be competing with importers who ship full containers of beans (300 bags).
If you pay a fair price to the producers, (do you have any idea what constitutes a fair price?) for a quality bean (how are you going to evaluate the beans?) you still have to incur shipping and storage costs and navigate the complex world of importation laws and practices.
Now you have to store, sell and ship the beans. Your price had better be competitive and quality high to sell in the specialty market. You are competing with companies with decades of experience in the industry and might be stuck with a product that cups marginally at best and must be roasted to the darkest levels just to hide its flaws.
My recommendation would be to go to work in a coffee shop or with a roaster to learn a lot more about the difference between a good and bad bean or to go to work for an importer to learn the ropes and develop skills, knowledge and connections. Otherwise you are just setting yourself up for headaches and failure, imo.
