Nick's (my sons) cremation Fund

I'm going through a parents worst nightmare. My son passed on Sept.20 th. He was only 31, he is survived by four children. I'm trying to raise the last bit of money I need for his cremation. After hurricane Michael came through our hometown last year we have absolved all of our savings in repairing our home. Nick unfortunately didn't have any life insurance. So I have taken on the responsibility of paying for expenses. I'm running out of time and just wish that this part was done. This is by far the hardest thing that I have ever had to do. Please assist me in the final arrangements for my beloved son.
