外贸中遇到的问题，请大家多多帮忙！

虽说我外贸以来也有几个月，可很多时侯国外贸易公司客户发邮件想合作，每次我都是要区分其真实性，通常客户这样发We are a wholesale trading company in UK specialized in sourcing andprocurement of products for our clients. We contacted you earlier about our new order but no reply up till now, wewill like to make a purchase of your company's product and i want abusiness relationship with your company. Please let me know:- Your minimum order quantity.- Your FOB Prices and FOB Port.- Your estimated delivery time. I need the best of service and i buy in large quantity and need all ingood quality. 我一般要想得知他公司名称，电话，传真，网址，地址等，当他没以上信息时我就以为他们是骗子，毕竟现在骗子太多，所以我就不想跟他们再聊，但就是怕有些是真实的，就错过很好的机会，不知我该怎么？再说要是真实的话也不知怎么跟他谈合作的事？毕竟他有可能不知道我公司到底生产什么产品？谁有跟国外贸易公司合作过有经验的请告诉我。
