美国采购需求：禽舍、钢结构仓库、集装箱房屋、洗手池、移动厕所

I'm looking for a container version of a 3-bedroom unit. Specifically, I'm interested in understanding the available designs and configurations. It would be great to know about the dimensions, materials used, and any customization options you might offer. If you have any recommended layouts that maximize space and functionality, please share those as well. Additionally, I would like to inquire about your lead times for production and delivery, as well as the pricing structure. If there are any minimum order quantities or bulk discounts, please let me know. Images or brochures of previous projects or models would also be appreciated to help me visualize the options. Looking forward to your detailed response!
