Cremation and Preservation Expenses

I am Elizabeth's little sister. I'm trying to help cover the cost of cremation and preservation of my sister Elizabeth Waite who passed away November 23 2016.  Have going threw this myself a year ago I know how expensive this situation can be and I am trying to help take some of the expense off of her wife Amanda Waite. Any extra money will be left to their 5 year old son John. Anything helps and would be greatly appreciated.
