I've got free room and board if your dad wants to make a trip out this way. I might be able to get permission for him to trap on a 3,000 acre farm as well.
In any case, does he have any suggested reading material on trapping 'yotes? I think I might have some underspring and coil spring traps that are big enough for 'yotes, and they have a nice light rust coating on them - ready for dye and wax.
