Funeral Expenses

This is my nephew Gage Hayes. He is 23 years old and is currently in hospice with just days to live. Unfortunately, due to him having Cerebral Palsy my sister was unable to get life insurance on him and is in desperate need of help with his funeral expenses. She is a single parent on a fixed income and has spent the last 23 years of her life caring for her son. Any help would be greatly appreciated.
