I'm way ahead o'ye.
I used to be an in-home cemetery salesman for 11 years and learned a LOT about the death industry.
Somewhere in my papers I have the plans for a knock-down shelving unit I designed (20 .. 30 ... years ago ?) that is glued and screwed to become a casket ... all soft pine and etc.
We in our Baptist church DO have the funeral in our church, all we'd need is formaldehyde and the car ride from the director.
You ARE way ahead of me! ;-) Thanks for the tip. Can you tell I really despise the death industry? If I had charged my estates like some of the funeral bills I have seen, I would have been disbarred years ago........
