Funeral wish for daughter who has passed away

In November of last year, our only daughter was diagnosed with the rarest of cancers; appendix cancer. She has 2 children & is a single mom. She had to quit her job & has no money and is not married, so we will be helping with her final arrangements as well as helping with the children when she’s gone.
She has been in hospice care for a couple of months now, and her hospice nurse has said that she is very short on time.... when asked how long, the nurse said weeks or maybe a month “if we are lucky”. Of course we pray for a miracle, and won’t ever stop hoping & praying, but we have come to accept this is probably her fate sadly.
.We have been trying to get as much time in with her before she leaves us, and have cherished every visit we get with her! We are SO BLESSED to have this beautiful girl as our daughter!!
We are financially strapped and are living paycheck to paycheck. We are having trouble with our own bills and have fallen behind.
She would like an open casket full funeral, so that her kids can get closure, and then she wants her ashes to be distributed in several urns. I want to make that happen for her; her last request. Please help us make this happen!
Full disclosure; I raised funds for her earlier this year and raised enough to pay her rent for almost a year. We had hoped to save money for the funeral and to set money off to the side for her kids, but her daily living expenses used up the donations .
At this point there will be no medical expenses, as she is in hospice and will never again see the doctor.
This money will go towards the funeral, flowers, her headstone (which we want to put angels on!) , expenses, and help with anything else that comes as a result.
If enough money is raised, I would love to set up a fund for when the children get older to go to college & for anything that we can do for them in the near future.
JESSICA IS NOW OUR ANGEL.
