Contracts through local-common markets (Little Upsilon)

how do you contracts to you'r own country?i got my own common market and i want to know how it works and will it make good money through you'r own contracts to the country it self.i want to know what it doe's,will i stuff up my sales?what i am thinking how it works is,to sell through you'r own country via contracts to you'r self is that the products that are sold through local-common markets contracts is that the products that are sold will go directly to the products in stock in the trade section.is that correct?if not please straighten me out a bit so i can understand how it works thanks.Anthony.
