Research for Chinese Retailers

I'm looking for Chinese speaking person ho can help me to find the contacts to the Chinese retailers.
We are in process of setting the sale platform for East Europe market. (Poland, Ukraine, Belarus)
How it will work?
Very simple: The retailer, producer, seller will have to sign in to our platform and be ready to post the items to Poland.
We are going to find the clients ho will purchase via our platform. Similar to "wish" or "alibaba"

I think that this task is going to be quite simple for you as you are going to use your language.
We are need a few contacts for our trials right now. The best will be to find toys retailers at first.
Any questions just ask
