I may be a bbq neophyte, but my day job is education. I would recommend you check out the nearest community college, college or university and look at their non credit programs. Most have classes for small business development, and most likely a class on how to write a business plan. In a few weeks you can have a pretty good idea on what is needed to develop a business plan. Best yet, with non credit, no tests. Just maybe a written plan that someone can review with you.
