Help with funeral arrangements

My sweet baby cousin passed away on 11/9 of pancreatic cancer. This awful disease moved aggressively through his body and today,  his mother, his family, his friends, and his children said goodbye. He was brave (and stubborn)until the end. His kids have been incredibly strong, their only comfort being that dad is finally at peace and finally reunited with their mom. They are barely adults and don’t deserve this kind of heart-ache at such young ages. My family is hard-working but you are never prepared for the unexpected. I’m hoping to raise some money for the family to offset the insurmountable medical bills piling up, in addition to funeral costs. This has hit our whole family hard, I just want to make sure his mother and children aren’t unnecessarily burdened. Anything is helpful and greatly appreciated.
