I don't have an answer, but I have an indirect connection to a customs agent who would be able to help handle things....for a price, which would need to be negotiated. This would definitely take some time to set up (I contact my friend who contacts her friend, etc. etc. etc.), but let me know if you're interested and I'll set things in motion. I'm thinking of importing a bike permanently to Ghana, and if and when I do, this is the man I'll use. He can travel to any border or port and do whatever it takes (again, for a price).
I'm on the road and internet is intermittent, but I'll get to it if I hear from you.
Hope that helps.
