Building chains

I want to start a business with the aim to increase the sales of PYMES and companies inside of our country, The most of the companies in México are PYMES and those companies hasn´t resources, knowledge, desire or volume to sale their products outside México, moreover, our local market prefer foreign products and our economy is damaged by several reasons. I want to move that scenario for the companies and their employees , increase sales and resourses inside each mexican company, my dream is about seek potential customers outside México, find potential suppliers inside México, negotiate with both parts and once i have the deal, buy to the supplier and sell to the customer the product with a fee over the invoice for my service, and deliver to the customer. The result of this deal will be: more sales for mexican companies assure to employees of those companies an income Reduce the risk to the companies of close their activities
