Android app for backend , delivery agents , franchise

I want to build a android app for internal use . I need the app to schedule pickups , assign deliveries etc. basically I will punch orders manually or sync with my web store . according to the location an agent will be assigned , the area manager will get a notification also he can track and followup with the agent. after the shipment is picked up , delivery options will go live. the same agent can also get assigned the job of delivery. during this time he will be shared address which he can open in google maps. all this can be tracked by area manager and admin. after completion of tasks the agent can view how much he earned today and when will the company pay him. a few more features I have in mind but will discuss with the developer directly. Prefer a developer from Pune. Thanks
