Help in marketing Brazilian Granite products.

I am soliciting for help in marketing our Brazilian Granite products. I have sent many inquiries and (http://maplered.com) contact numerous distributors (more than 200 in the US) without much success. I would like help in marketing my products as how to contact, who to contact, organizations that would help me promote our products (The Brazilian Embassy seems to have gone into hiding) or whatever else it takes to get our products into the international market. We represent small and (http://maplered.com) medium companies that cannot export themselves and (http://maplered.com) have many fine products to offer. We do represent one company that has exported, but wants to open new markets. Any ideas?

Thanks for your help.
