While at PizzaExpo in Las Vegas I sat in on a seminar about how to write a business plan for a pizzeria, it was hosted by two guys from "restaurantowner.com" I believe there are several templates to choose from and I got a copy of "Paulie's Pizza LLC" during the class and I think it's just what you need. From memory I think it cost about $100, check it out.
Sorry there are no phone numbers on my copy, only the web address. Write back if you have trouble getting the information you need.
