Hello, everyone!
I work for a consulting company in Shanghai, called Opportunity Guide (http://www.opportunityguide.cn).
I can help you find manufacturers in China, for any kind of product. Just keep in mind manufacturers usually work with larger quantities and have minimum orders.
If you have a request or doubt, feel free to email me at anytime mariana@opportunityguide.cn
I would answer your email as fast as I can :)
