印度尼西亚采购需求：建筑标识、导视标识、方向标识、槽形字母

I'm interested in placing an order for your advertising light boards. Could you provide me with details on your available models, including options for customization? I'd like to know about sizes, materials, and any specific features that stand out. Also, it would be great to understand your pricing structure, minimum order quantities, and lead times for delivery. If there are any ongoing promotions or discounts, please include that info as well. Looking forward to your response!
