Android Taxi Booking and dispatching apps - repost

I want to buy the source code of a taxi booking/dispatching Android mobile apps or have one built. I am looking for a complete automated taxi solution with: 1. Rider/Passenger Taxi booking mobile app uses GPS to send Rider location to the server app, rider should be able to create a login and use it to store his preferences like addresses and contact numbers as well as email address, Rider app sends GPS coordinates when a booking is made 2. Driver mobile app to receive jobs, accept them, get rider's contact info, use map to locate addresses. driver should be able to sign up to the service and gives a credit card as a deposit, he should be able to login when using the app 3. Server app and database to store all driver and rider info and trips info, to dispatch jobs to drivers, to send confirmation to riders... 4. Server app will utilize GPS to locate closest taxis to the rider 5. Mobile Web Portal to help those riders without Android to make booking online.
