Malcorvus Flint would be interested as a financial backer but he'll want first dibs on anything magical for research purposes and/or donation to museums. Good chance he may decide to accompany the expedition, depending on when its scheduled to leave (he does have teaching obligations till school term ends).

Edgar Minks will also be interested in financing for part of the take. Mostly so he could turn it around for a profit but officially to donate for a good cause/musuem depending on what's found.
