Eberle,
First, on your tag line...Amen and Amen! Saw Lone Survivor last night and every American should see that...to appreciate and understand the price of our freedom and the men and women who lay it all on the line.
Have been to Africa a couple of dozen times on business and had the privilege to hunt there twice. Both times the hunts were organized by my local friends. Generally you pay for your room and board and then an additional fee for anything that you kill or wound. Tips are additional...PH, trackers, skinners, cooks, etc. One thing I have found that are really appreciated by everyone as tips are good hunting knives!
On taxidermy...you can have it mounted there and shipped home, or shipped home and then mounted. Either way, the cost is about the same...over there, the taxidermy is a bit less...but then your shipping cost of a large crate is more than just the head, horns and cape. Also the cape has to be decontaminated there before is can be shipped abroad. Both of my trophies were done over there and very pleased with the results. One was an Impala and the other a Kudu, which was mounted with the mouth open.
