Please help me cremate my brother

My brother John king home was involved in a house fire on August 20, 2017. He was able to get out but with 81% of his body With 3rd degree burns. On the 2 day he was there the doctors told me that there was over a 100% chance of him not making it. With numerous surgery’s and against all the odds he had come as far as being release from Tampa General and moved to rehab doing very well in rehab we had a date too come home on December 15th my husband and I started building a addition to our home as he would need 24 hour care so he was doing his rehab walking with a walker doing very well then on December 1st I got a call I wasn’t expecting that my brother had passed away. My brother John ended up passing away from Ammonia which lead to Respiratory failure. So please if anyone can find it in there hearts to help me with cremation expenses I’d be forever great full
