Sourcing in China about promotional products

Hello, I have a 3-year sourcing experience, may I have a honor to work for you? As a Chinese, There are many many sourcing freelancers. But they don't have HK company. I have. As you know, some freelancers ask commissions from suppliers and the price or quotation will be higher. The freelancer company often get money from your HK company. My HK company can make a legal contract to limit our behaviours and ensure mutual benefit.
