客户要我帮他清关问题，我需要怎么呢

客户今天发来邮件说要我帮忙一下清关问题，他不懂报关，清关，之前一直是走快递的。我也不清楚我需要哪些事情，所以问问大家，以下是邮件原文： I he also found a manufacturer for my men's caps there in China (Hong Kong), but they typically only provide a FOB price and I may need someone to handle shipping to my door. They he a minimum order of 600pcs, so the shipment will be larger than I am accustomed to and I think will incur customs charges. Would you be willing to arrange and handle shipping for me, because I am unfamiliar with freight and customs charges when importing from your country.I would rather pay you and deal through you for this complete service to my door, if possible. 希望有经验的大侠帮我一把。 QQ：1731561333 注明：清关 上海，香港货代欢迎来沟通！如果不了帮助的，请勿加咯，大家都挺忙的。
