Chinese bidders only!!! Internet marketing for an Italian food trade website

Last month I published a well-performing-SEO-based technology-based website in 7 languages, [login to view URL], dedicated to information and promotion of reliable, certificated Italian food industries and food-related services providers. I need link building, lead generation, internet marketing to be specifically targeted to food importers, food wholesalers, restaurant and food service chains based in the People's Republic of China. Looking for cost-effective proposals, as to start efficient synergies with Chinese freelancers only. Many thanks indeed Dario
