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 to get a flyer produced, and I would appreciate it if you could send me some options. Could you provide details on the available sizes and pricing? Additionally, if you have any recommendations or sample designs that would help in making a selection, that would be great. I'm particularly interested in understanding the materials you offer and any customization options that might be available. If it's possible to get a bulk order discount, please include that info as well. Looking forward to your prompt response so we can move forward!
