Jane Rogers funeral service

Hi, I'm Katie, Jane's daughter, and I'm having to plan and pay for my mums funeral after her unfortunate and sudden passing. She battled with many illnesses for so long and unfortunately was uninsurable when times where at the most uncertain and ultimately died of something unexpected, this means the burden of paying for the funeral falls to me and as I was her full time carer and a single mum I have no savings to dip into and no other way to raise this kind of money so she can have the simple funeral and cremation that she wished for and I can't set up a payment plan with the funeral directors either as they need to be paid in full before we can have a service for her. Please help me and my brother give our amazing mum and our chidren's doting grandma the funeral she deserves after being the most caring and generous person I've ever met even during the worst times of her life.
