Joey Delarosa's Funeral Costs

On September 12th (Tuesday night) Joseph De La Rosa lost his life. My mother found his body at the bottom of the pool at the Fishermans Retreat for Rvs and camping, where they had been living temporarily. We are still unsure about what caused him to drown, but what we do know is that he was found wearing his glasses and Beats by Dre headphones. So there is a major possibility that he might of had a health emergency and fell into the pool rendering him helpless to save himself from drowning. This is a devastating loss for all of us, because my father was only 46 years of age. He was a great protector and always kept us safe. He was joyful, always telling jokes and making us laugh. He kept our spirits high.
In these past 3 years our family has suffered tremendous loss. First, in 2015 there was the sudden death of our grandmother, our grandpa died the next year 2016, and now we have lost our father in this tragedy. For my mom she has lost her mother, father, and husband. Now we are all she has left. My mom and dad always had each other throughout every struggle. Since we were all older now they had more time to spend together and had even talked about going on a vacation together someday.
What is heartbreaking is how my father never got the chance to be a grandpa and spoil his grandkids, or walk his daughters down the isle on their wedding day, or grow gray and old with my mom.
Now our family is left with another challenge, we have been going through financial struggles and my father did not have life insurance.
Since this was such an unexpected turn of events we are left attempting to pay for all of his funeral costs. This includes: grave plot, headstone, church/funeral services, and his transportation from the church to the cemetary.
Also, because we are uncertain about the exact cause of death or drowning, he will be undergoing an autopsy, which could take 2 weeks and will cost anywhere between 3000-5000 alone.
We greatly appreciate any and all help.
