So perhaps you need to present them with a more complete solution. Develop or source a faster laser cutter. And find a small factory in an area with skilled labor (central North Carolina still has people who can cut & sew). And develop a process in the factory to keep all the panels for one item of clothing together from cutting to sewing to shipping (maybe a bucket?).

It'll be a bespoke item at premium prices, no question. How big is the market for this? I don't know, but my feeling is that it's older women.
