Sister Second heart transplant

This is my little sister. She has just had her second heart transplant. She recently moved to Vegas and hospitals there were not able to give her the care she needed so she was flown to Cedars Sinai. We will be so grateful for help with  costs of the medical bills, and she will have to stay within 30 miles of the hospital for quite a while. So she will have to stay at a hotel until she is stable enough to go back home to Vegas. My sister has been the most generous caring amazing woman, I would love to be able to relieve some of her stress regarding the mounting bills. Any help is so incredibly appreciated. Over 12 years ago my sister got a virus while working as a nurse that destroyed her heart and the heart of he unborn baby girl. They both needed transplants at the same time. The baby got a heart however died 8 days before her second birthday. My sister then got a heart and it lasted about 12 years. She just received her second one . Thank you so much in advance.
