How should I start a coffee export business? I am from Yemen, one of the world's best location for coffee.

I want to start the coffee business and start a coffee export business but I have no experience in exporting and no customers to export to. Can somebody help how to start this coffee export business? What should I know and how to start?

I am good with business (export process and LC and so) but I have no idea who buys coffee and how to approach them?

Please help.
As another dimension, I see a few trends that you might wish to consider.


Green beans. More people are getting into home roasting, and green (processed but un-roasted) beans are the vehicle. Also, green beans store better for longer time (e.g., freezing) so you can capture a particularly good "year" or crop of beans for a longer period of time. Even whole, unprocessed cherries might be an interesting notion. 
Skins and pulp. People make beverages out of the (usually discarded) fruit skin and pulp, called cascara, qishr, or other names. These are difficult to find dried, and perhaps impossible to find fresh.
Direct marketing. Another trend is (broadly) the "farm-to-table" strategy, where roasters or cafes will purchase beans directly from farmers. There might be good business in brokering "direct" deals like this, by helping responsible farmers with good beans get good prices by selling directly to the end user (e.g., a local roaster) instead of through an aggregator or warehouse. You could seek out some exceptional beans with unique qualities and get those farmers into the specialty direct trade market. 


Just a perspective from a "consumer" standpoint.
