I think business templates are useful to look at, but not necessarily to imitate. RBC has a really great, thorough article on creating a business plan that also provides samples. I'll link to it below. It's really good to look at samples but ultimately your business is going to be unique, and will need a unique business plan. I'd strongly recommend creating one that caters to your needs. I've also found some other information on the importance of branding that I think will help you if you're starting a new business. Good luck!

Business plans concept is in change. Check http://www.businessmodelgeneration.com/canvas or get the book. Very useful for start-up, growth or just for a simple idea planning. This concept is simpler and clearer than regular business plans. It has the same procedure but with different thinking concept.
