Ankesh,
I know it's not what you're Looking for But since very few Unexperienced Entrepreneurs will be able to Realalistically become so called "Rich" based on a $100. business idea...
My Suggestion is to Start Applying the following Non-Hype method into your Life as I've mentioned a few times before...
Start getting Smart & Rich for about 2 Bucks for a Used copy...
