Kidney transplant

Hi my name is Diana my husband has been a mechanic all his life working hard using his hands been a father of three grandpa to 1 and for the past 7 years he’s been going to dialysis 3-4 times a week which really drains the life out of him. We recently went to Mayo Clinic to sign up for the kidney transplant trial but they told us we’re going to need a minimum of 10,000 to be able to live in Arizona for two months while he recovers IF it happens. We are just looking for any help from anyone out there thank you and we appreciate you
