蒙古采购需求：智能互动白板，交互式白板，液晶互动白板，广告机，健身镜，条形液晶显示器

I'm interested in a custom smart mirror with LED lighting and signage for our restaurant in Ulaanbaatar, Mongolia. Key requirements include a large wall-sized smart mirror featuring LED backlighting and the potential to connect to AR or interactive software for guest selfies. Additionally, I'm looking for custom LED signage displaying "WALLSTREET" with a backlit golden glow, as well as LED linear lighting for both walls and ceiling similar to modern interior strips. Could you please provide an estimated price for one unit of each item, the production timeline, shipping options and costs to Mongolia, as well as warranty information and any installation support you might offer? I've attached a reference image for design inspiration. Looking forward to your details!
