Help Cover Dustin Arnold's Final Arrangements

My little brother, Dustin Arnold, died suddenly this weekend. My family is absolutely devastated, and we don't know how we're supposed to move forward. Our dad, a retired Air Force veteran, can't manage all of the arrangements on his own on a fixed income. Any help would go a long way. Anything left over from making my little brother's arrangements will go toward supporting the family in this heartbreaking time.
