斯里兰卡采购需求：无人机、第一人称视角无人机、遥控车、漂移遥控车、遥控飞机、机器人玩具

I'm interested in acquiring drones in bulk for my upcoming project. Could you provide me with your wholesale pricing, available models, and quantity discounts? I'm particularly looking for options that have good quality specs and are suitable for commercial use. Additionally, it would be helpful to know about the lead time for orders and whether you offer any warranty or support services. If you can send over your catalog or product sheet, it would be greatly appreciated! Looking forward to your response.
