any of the usual mold makers will make you a custom mold based on your design im pretty sure, but expect to pay a fair bit more for it to keep it exclusive to you. you have to pay the full design costs plus the machining costs.
as far as bags go, best prices i have seen are from Johnson Bag, around $200.00 - $250.00 per colour plate (2 colours = $400 - $500) plus 10,000 bag min order. So, about $500 for plates, and almost $800 for bags.
