美国采购需求：铝合金门、铝合金窗、推拉门、平开窗、入户门、车库门

I'm looking to purchase a sufficient quantity of windows for 9 tiny houses that I'm planning to set up. These houses will be located in the US, and I'm interested in exploring various styles and specifications that would best suit the tiny house design. Ideally, the windows should be energy-efficient and durable, considering the diverse weather conditions in different regions of the country. Could you provide more details on the types of windows available, along with your pricing, minimum order quantities, and lead times? Additionally, I'd like to know if you offer customization options, such as different sizes, colors, or finishes. Understanding the shipping options would also be helpful, as I want to ensure a smooth delivery process to my location. Looking forward to your prompt response.
