Funeral Expense For Michael Alston

My dad is has terminal cancer. The doctors have given him a month by the size of his body and not eating. He doesn’t have saving, 401k, retirement, property, etc. I’m the only one responsible for his care, and I feel I owe him at least a cremation. I would love to do a cremation and viewing. He will receive $255 from social security. Far from the $800 for cremation or the $2500 for the viewing and cremation. Any help would be appreciated. Thank you , Todd
