Online Taxi Application (Android Driver & Rider), Web based Dashboard Admin

I need a Functional POC (Proof of concept- only for Demonstration) for Online Taxi. It needs to support only 5 Drivers and 5 Riders and never made to run in LIVE Market. We know that a person who read this cannot make Uber or Ola Taxi. Preferring only Developers having Functional Module with them. No Scope for NEW Developers. Need Demos APK and Demo Web Dashboard to verify. Need POC at lowest cost, don't need source code only condition is to be functional. After you show DEMO APK, DEMO Dashboard, I have a Offer for you. Offer will be only only to the Lowest Bidder with functional demo of Application. Features Required as in the Attachment Rider should be able to see the GPS nearest Driver and should initiate CALL to the Driver - though FCM Firebase Cloud Messaging (FCM) Driver App should be complete native, Rider can be Hybrid Admin Dashboard to Manage 5 Drivers and 5 Riders
