Great question darthtrader, mainly because the same thoughts are going through my own head. I have a loose five year plan for entering the market as a vendor. I know my initial setup cost will approach $20,000 most likely. That is why it is a five year plan! My only advice to you as a NON caterer/professional pitmaster is this: make a choice to do it, or not do it. When you make the decision to do it, go after it with a vengeance. Do everything with all of your God given ability. Obviously you can Que based on the initial question. Don't do anything half @$$ed. This is the American Dream, to have a passion, pursue it, and make it your living. Good luck brother!
