Funeral Expenses for Jason Roller

My son, Jason  Roller, has been moved to hospice to live out his finals days.  After he has left us and joined our lord, we will have him cremated.  We are also trying to plan a modest service to honor him, especially for my three beautiful grandchildren that he leaves behind.  I am asking for any help that you could offer.  We are estimating $1500 to be the cost.  Any moneys over that amount would be given to his children.
