Glenn Harrison's Funeral Expenses

My name is Adriane Gavrock, I'm Glenn Harrisons wife. He passed away very unexpectedly on January 17th at the age of 56. I lost my love, my life, and my soulmate. As much as I dont want to think about it right now we had nothing set aside for final expenses. I would like to ensure that his final wishes were carried out.  Any and all help would be appreciated. Thank you and God bless.
