Sales Business Plan

And where can I view examples of business plans?

I am writing a business plan and I need to show that the plants I want to sell are still selling strong despite the drought and economic downturn. I am specializing in drought tolerant plants that are used at most new businesses. I need the most recent plant sales and pricing information.
I am also looking to find out about the other nurseries in my county. Most of my competition will be small family owned businesses and may even be operating without a business license.
Anyone know any good websites?

I am good at picking stocks. Someone wants to hire me to take control of their online stock account and choose stocks and buy them online for them. Am I allowed to do this now or do I have to get a business license and financial planning certifications?
