沙特阿拉伯采购需求：2000瓦风力发电机、5千瓦风力发电机、哈沃特风力发电机、螺旋式风力发电机、家用风力发电机、新型风力发电机

I am interested in obtaining pricing details for vertical wind turbines with capacities of 5KW and 10KW. Please provide me with your best quotes for both options, including any bulk discount considerations. Additionally, I would appreciate insights into payment terms, warranty information, and the technical specifications that come with these models. Furthermore, I'd like to know about the shipping costs and estimated delivery timeframes for delivering the products to Pakistan. If possible, share any certifications or compliance details relevant to these turbines. Your prompt response will be greatly appreciated as I plan to move forward with this project soon.
