美国采购需求：电子动画会说话的树，树人，定制产品，公园配套产品

I'm in the market for a product that stands at approximately 4 meters tall. This height is crucial for my current project, and I'm looking for options that fit this specification. It would be great to know more about your available models within this height range, including any relevant features or customization options you might offer. Additionally, if you could provide details on material types, any certifications or standards met, and typical lead times for production and delivery, that would be super helpful. I'm also interested in pricing information and any volume discounts that may apply if I decide to order multiple units. Looking forward to your response!
