Brent liver transplant

My best friend Brent Shaffer found out 2 years ago that he had cirrhosis of he liver,he's now enrolled at Florida hospital transplant center and his liver is failing .he has to 6-12 liters of fluid removed from his abdomin every 8-12 days and fluid off his lung every 2-4 days ,his insurance will cover the surgery but the rejection meds will cost tens of thousands of dollars and his insurance won't pay for it.he has to have a minimum of $50,000 out of a possible $150,000  in a account that We have set up for him before they do the surgery,please help my buddy. every dollar is a step closer and without it I will lose my best friend of 40 years .thank you so much and God Bless You ...
