The costs add up but you can spread the money over time. First you pay for the airfare and hunt. Then 6-12 months later ya pay for shipping the trophies home at, say $2000, then pay tanning pretty soon and spread the taxidermy over a couple of years. Dosen't hurt as bad.
One can hunt South Africa on package hunts pretty cheap, under $10,000 all in for the hunt and airfare.
