Looking for a superstar sourcing/shipping agent in china.

We are looking for a shipping agent or a 3PL company in china who can hold our stock from our alibaba supplier and ship it directly to our customers in the USA. We are looking for someone reliable with substantial experience in ecommerce and drop shipping. We have a private labelled brand but we will occasionally require sourcing from chinese marketplaces such as alibaba and 1688. If this sounds like something you can do then please apply to this job.
