alibaba is your key. It will surely help you solve your problem.
I would recommend Global Sources too. Not only you can find more trust-worthy suppliers, you can actually get some free education on how to source! For example, they have a guide on sourcing, finding suppliers, how to negotiate with them, how to manage quality control etc: http://www.globalsources.com/SITE/BUYERGUIDE.HTM
Besides that, another resource I found it quite useful is their Top 20 products. I believe many of us would want to look for high demanded products or products that are most sourced for right? So here's the information that's updated monthly: http://www.globalsources.com/ST/20-Most-Popular-Products.html
