美国采购需求：土地征用、商业用地购买、工业用地出售、土地投资机会、土地开发服务、购买商业用地

I'm interested in getting a quote for greenhouses, but I need a bit more detail to make an informed decision. Could you provide me with the price range for various sizes and designs available? Additionally, I'd like to know about any customization options you offer, as well as the materials used in construction. I'm also curious about the delivery times and any bulk order discounts you might have. It would be great if you could include information on warranties or after-sales support as well. This info will really help me compare options and decide how to proceed. Looking forward to hearing back from you soon!
