This is an awesome Idea. Always looking for something like this. Cab rentals are too high.

You can talk to Cab Service Providers in different cities. And don't worry about monetizing. Once you have a good userbase, you can charge a minor amount from Cab Service Provider or even users when they book a Cab (and its actually saved them some bucks). No one will mind giving 1 buck each time they book if it is saving them 10.
