荷兰采购需求：自动化、Ewellix行星滚柱丝杠、工业自动化、KGG行星滚柱丝杠、行星滚柱丝杠工厂、行星滚柱丝杠制造商

I'm reaching out with a couple of inquiries. First, could you please provide me with an estimated cost for four units of your product, including delivery to our address in the Netherlands? It would be helpful to know the total cost and estimated delivery time. Additionally, I'm interested in knowing if you have the capability to manufacture custom-designed steel machinery structures. Any details on this would be greatly appreciated. Looking forward to your response!
