斯里兰卡采购需求：20w涡轮机，风力涡轮机玩具

I'm interested in obtaining a price quote for your products, including the delivery fees to Sri Lanka. It would be great if you could provide detailed information about the pricing, including bulk order discounts if available. Additionally, if you could share your estimated delivery timeframes and any other relevant shipping details, that would be very helpful. Looking forward to your prompt response so I can move forward with my purchasing decision. Thank you!
