Brad:
Based on my experience over there, if you have a hide tanned locally it will probably be done by wet or dry salting -- reasonably effective, but not the best processes for sure. In the larger cities, you might find a tanner who would employ the chrome or vegetable crust processes. If your travel schedule requires you to leave the country before your hides are tanned and ready for transport, it goes without saying that you will need a local representative whom you trust to collect them from the tanner and insure their proper shipment.
Good luck, and good hunting on your trip! I envy you.
