美国采购需求：可扩展集装箱房屋，可扩展房屋

I'm looking for pricing on foldable and flat-pack container houses in various sizes. It would be great to know options for customization, especially for features like kitchens and bathrooms. Could you provide a detailed breakdown of pricing for different configurations and any additional features available? I'm interested in understanding the overall cost, lead times, and shipping options as well. Thanks!
