Items like insurance, etc. can be sold for the big bucks.
If you want to start a business to be your full-time job, I recommend getting a masters degree in whatever you want to do so investors will take you seriously and find a niche that the big, local companies could use make use of your services.
For a side business, if you have some sort of a rare talent that you enjoy doing (great with photoshop; can tune a derailluer a quick as anyone; a scratch golfer; a tech wizard, etc), you can make some damn good cash in addition to the 9-5.
