Need Custom DAM

I need a custom down air mat made according to the specs below. I have 6 oz of 800+ Goose Down but need a craftsman to build the air mat for me.

Kookabay.com appears to be (temporarily?) closed for business. Who else should I consider?

Specs:
– width: 30"
– length: 80"
– thickness: ~3"
– shape: rectangle
– warmth: comfortable in the teens

Thanks :)
