On Demand Courier Shipping Android App Development

I need an Android app. I would like it designed and built. Source code will be my property. Don't bid if you don't want to accept my terms and conditions. Project will be awarded after checking your 50% Work and milestone of 50% will also be released. Remaining 50% after giving me fully functional source code. If you think, you can develop this website as per my requirements mentioned below then please ping me. Source code will be our property. There will be two panels in one App Delivery/Pickup Team Panel Customer Panel Admin Panel Webpage Selected candidate will have to develop an Android/iOS App or Website with backend for delivering anything within 120 Minutes, which will be similar to Cab Booking App. But in this app or website, we will be showing Delivery and Pickup Boys instead of Cabs using Google maps geo location. Price should be calculated based upon the distance from to To location. Suppose, customer has to ship anything and they don't have to go anywhere to handover their couriers to any courier agency. First of all customers will have to submit their details of packet, what is the weight of the packet, what is the content in the packet, what is the value of the packet, where it needs to be delivered, from where it needs to be picked up and at which time, pincode of delivery location. After submitting all these details, pickup boy should be visible on their app on map with their exact distance in minutes. Then customer should select any delivery boy and confirm the booking by making a payment of 25 INR if parcel needs to be shipped locally and Rs .50/- if parcel needs to be shipped intercity. Price should be calculated automatically alongwith GST of 18% Extra. After this a new page will open on our app and details of pickup boy, its exact location, its distance from customer location, coming with two wheeler or four wheeler will be displayed to customer.
