瑞典采购需求：挑战币、钱币收藏、收藏币、金币、古币、银币

I'm looking to order a custom coin brooch featuring my design and need some details before moving forward. Could you provide info on the minimum order quantity, production timeline from design approval to delivery, and acceptable design file formats? Additionally, I'd like to know the pricing per unit at different quantities and the shipping costs to Sweden. Your prompt response would be greatly appreciated!
