I am also a "huge conservationist". Hunting is an important part of conservation for many species (lion, elephant, etc.). People that say otherwise are either poorly informed or promoting an agenda.
It is odd that a new poster would sign on to an obvious hunting site and ask about obtaining a mount of an animal that was not taken by a hunter.
And to top it off the OP asks about potential illegal actions! Maybe this line of inquiry is well intentioned - but maybe it is not. It smells rotten to me.
