I don't the problem, Huzefa, is the insulation of the quilts, but the details.
You list a clo, but we don't know what that means. I think it's 40-45ish?
I don't know how I would close the quilt under me. Just a tuck method?
What's this omnitape footbox?
Both you and your quilts are, to a large extent, unknowns. Waiting for an order of 15 could take awhile before production starts. There is no reputation to go on here, so we need as many details as possible and a great price (you've more than nailed that). If you could start production sooner, I think that might give people more incentive as well.
