Also, I would think twice about shutting down a business for any length of time that is making money, especially if you plan to expand it and especially if you're not expecting a major capital infusion from another source (investors, etc.). Expansion costs money. If the business is making it, than keep it running. You'll regret it if you don't. You don't want to lose your momentum- expansion means higher expenses which call for higher profits to cover them. You not only have to continue to do the business that you are doing to justify expansion/ capital investment, but you have to do MORE business or you'll wind up working harder/ spending more for less or the same money and that is a recipe for failure.
Think about store front businesses (Pizzaria's, deli's, clothing stores, etc.) that epxpand (Maybe blowing out a wall connecting it to the store next to it or moving to a new location) they don't shut down for renovation. Instead they hide the work with big tarps and sheets and put up signs that say, "Please excuse our appearance while we renovate and expand our business to serve you better", or some such. They don't shut down and put up a sign that says, "Sorry... we're closed for six weeks to expand and serve you better...in the mean time, go spend your money some where else."
