Need help with Liver transplant expenses

My husband has been sick for a year now and in need of a liver transplant, he has been in and out of the hospital this year . He is now on the list for a liver transplant. Anytime now we can get a call from the hospital in San Francisco once they found his match. After the surgery, we will have to live in San Francisco for 30 days. We will need to rent a place close to the hospital because he will have lab works twice a week and follow up appointments twice a week too. They required us to live close to the hospital after the surgery. We live far from the hospital, so we do not have a choice but to rent there in San Francisco. I am the only one working, and we cannot afford to pay another rent for a month. My husband is very weak and want the the transplant sooner. But I am worried about not being able to pay another rent from my only income. Any help we could get is greatly appreciated. God bless you all. ❤️
