Replying to [adali]:
If you contact the suppliers and let them think you are a buyer, this is not good and soon your name will be known to many suppliers as a guy who is messing about, the fact is the suppliers want to make money and get a order, maybe dont have the time to give you info on their company, well true info.
How can they know who you are, maybe feel you are anther supplier in China?
There is a way to abtain this information and make the supplier happy, we have done this type of work in the past, we used our export office in china to arrange, if you like our help contact me.
