On a related post, I am toying with the idea of starting a photo tour company (which have become quite popular in recent years with the explosion of interest in digital photography). Would have to start with some short (3 or 4 day) local Arizona tours (Sedona and Grand Canyon, etc). But a long term plan would be to do a wild cat photo tour focusing on captive facilities in western Europe. Three days at Parc Des Felins in France, a day at Zoo Zurich (for snow leopard and amur tiger enclosures), a day at Wildlife Heritage Foundation in UK for big cats, a day at Port Lympne in UK for big and small cats.
