Memorial service and cremation

My ex husband and my children's (Daniel and Joe Stewart) father is passing of cancer. He has no money for a small memorial service and cremation. He is currently in hopice and only has a few days to live. That last ime he was coherent he cried that he did not want a paupers grave and wanted to be cremated. My children would like to have a small service for Jim's friends to come to pay their last respects. We need help getting the funds together to accomplish this so I am reaching out to others to help my friend of 40 years. This has been an extremely difficult time for all of us and so we are seeking help from friends and family.
My children and I appreciate any help that you can give to Jim.
