corbomonster,

I'm very sorry but I am not going to be able to help you with a kilt under $100.00

The fabric and materials (straps/buckles, thread, Molle webbing, etc.) alone, for a kilt in solid colored Poly/Cotton fabric, are over $50.00.

Paying my staff a decent living wage, paying the electric bill and all the other things needed to keep a kilt shop open, would mean that they would need to be able to make your kilt in less than 2 hours.

I'm sorry, but I just can't realistically manage that. I guess your best bet is to find someone with no overhead, who is importing their stuff from somewhere that $4.00 an hour is a working wage and who requires each employee to produce 10 garments per hour.
Don't give up hope. I get emails every week from the companies selling many of the exact same garments you have been asking about. The going rate for one of these imports is $12.00 us dollars.
One of these companies is bound to take up your idea, and flood the market with them, very soon.
