Expanding a timber mill in West Africa to International

I own a decently sized timber mill in West Africa. I buy logs for the locals and then mill them into sheets, boards...etc. I currently sell to the domestic market but there isn't that much of a demand as cheaper quality wood is preferred domestically.However, European countries, China, USA, and many others are very interested in importing timber mostly as logs which I do also supply, this is evident from the large amount they import from neighbouring countries such as Liberia. I tried to google who the importers are but couldn't really find any company names only data about imports and exports. So how would one approach expanding into these international markets? Would you try to contact companies and hope they would be intersted? Or is there a marketplace for this kind thing? see hubwealthy.com/wealthy
