I know somebody who buys random computer parts off of ebay, yard sales, people throwing computers out, etc. and builds computers from the parts and sells them off of his local cable channel (ch 10 in my area). Most cable companies will give you cheep (or in our case free) crappy little advertisments on the local cable channel. So that is a way to get off of the ground at least because once people know that you sell quality for cheep and know your stuff, they are apt to come back...
