Funeral costs for my father

My father has been struggling with a lot of health problems for a few years now, and over the past 10 months has experienced a rapid decline.

He had a double bypass surgery in January following a massive heart attack. It was his 3rd heart attack to date. His recovery was very complicated and he was in and out of the hospital, nearly dying a few times. 

As of today, he was admitted to the hospital yet again on Sunday night for what was believed to be a 4th heart attack. Turns out it was related to his struggle with AFIB and heart failure. I received a call from the hospital at 1:30am last night informing me he had been found without a pulse and was intubated and they were struggling to keep him stabilized. The result of this was him passing away at 10am. 

My sisters and I are now struggling to come up with the funds to cremate him, bury him with our mother (who died in 2011), and have a nice funeral service for him. 

Anything can help us right now. Please help.
