Brainstorm keyword phrases around that niche and go to http://freekeywords.wordtracker.com to see how many searches people are making for those keywords (will show you demand). This will help you whittle down your business idea. I would also go to www.innoventum.com. They have a free pdf you can download that gives you every detail you need for starting your first business.
