I have been living in China for the past 7+ years offering freelance services to companies locally and internationally.
I can be anywhere in China within 24 hours (unless I am already booked). This is very useful to many companies who need a guy on the ground in a hurry.
Don't take any risks. You need someone to keep an eye on things here otherwise the chances are high that you get a container load of goods that are not up to our standards.
