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 interested in exploring the range of home sizes your factory offers, specifically between 400 sq ft and 1200 sq ft. I'm looking for details on different models, configurations, and any custom options available within this size range. Could you provide information regarding the features, layout variations, and pricing for each of these home sizes? Additionally, if there are any promotional offers or new models that you think might fit my needs, please share that as well. Understanding the specifications and options will help me assess which homes align best with my requirements. Looking forward to your response!
