I used Business Plan Pro 2007 to make my plan. It has quite a few sample plans. It will create an outline of all the components you need for the plan, will tell you what should be in each spot, and give example text from fake companies. It'll also automatically generate graphs and a table of contents.
I really had no idea what I was doing before I started writing my plan, but that program made it ten times easier. You should look into it.
