Business Plan: Looking for help

Hey guys, believe it or not, i never did write a business plan. I kept it in my head and it has worked out well. Problem is... banks don't like the whole " it's in my head" concept

I am wondering if anyone has a business plan that they wrote, not that I can copy obviously but one that I can use as a general outline to write mine.

Or, you may have a suggestion on how to write mine. Thanks.
