Charles I heard about your situation,best of luck and prayers.

EKM,
You might wan't to have some one who is trained as a EMT in camp for health issues regarding the level of problems that could arise.You will probaly need a saftey saddle forclients or gueststo ride on.Also you might want to have a gaurdian,or partner with them that know them and any special circumstances that could arise.
I have taken kids with some levels of disabilitys hunting on more than one occastion,and the level of gusto that they have and enthusiasim is mind boggling so best of luck keeping up with them and I hope you make someones dream come true.
