Assist in Grandfather's Unexpected Farewell Costs

Hey guys! My grandfather passed away on June 27. We were told we had a month or two, but that sadly turned into 6 short days. He did have a burial policy but it only covers a small amount of the cost. Our family is stretched thin trying to get his children here from different countries and states on top of having to come up with the money quicker than planned. Any help is greatly appreciated.
