Michelle Smith funeral arrangements

My sister Michelle is a beautiful person. She had cerebral palsy since birth and was in a wheelchair. She gave birth to 2 beautiful girls whom are 8 and 7 now and very strong at this moment. She always helped people if she could. A place to sleep, food, a bath. Shes diagnosed with breast cancer 8 weeks ago and had 2 rounds of chemo. She caught a cold that developed into pneumonia. She is hospitalized and in the ICU for 5  days to treat the infection. When they tried to wake her up, she had a stroke. It made  her a vegetable and depend on life support and dialysis. She came home in hospice care and passed away 12 hours of being home . We are getting screwed over by the insurance company and they do not want to pay for the funeral expenses. I would love to lay my sister to rest as classy as she is. Please help me give my sister a proper going away. Thank you everyone that helps.
