Hi:
Already some solid info here, but I would add two things:
1. Explore what kind of startup courses are offered within your community. These generally offer the basics in creating a business, tie you to local resources (and maybe mentors) and are reasonably priced.
2. The Business Model Canvas is a great place to start working through what you need to know to create and build a business -- it's available through strategyzer.com.
If you wish to discuss, send me a PM through Clarity for 15 free minutes.
Cheers,
Kerby
