Courier Service App Like Uber (please mention time needed to built as well)

I’m launching a same-day courier service across the UK that moves only small parcels in our fleet of Minis. To run the operation smoothly I need a full Android and iOS application split into two experiences—one for customers, one for drivers—built around an Uber-style model with live dispatching and tracking.

Customer app – must provide:
• Real-time vehicle tracking
• Package scheduling (on-demand or in advance)
• Integrated payment gateway for card and wallet options
• Automatic distance- and time-of-day-based price calculation shown before checkout

Driver app – must provide:
• Turn-by-turn navigation assistance to each stop
• Ability to accept multiple runs in succession
• Earnings dashboard with daily and weekly summaries
• Customer rating & feedback after each delivery
• Mini cars only be able to register to the APP
• Option to offer 5% exta income if they stick 2 little stylish stickers on the car

Both apps (built in one, customers' and drivers' side and login) should share a single back-end so that bookings, routing, pricing and payments stay perfectly in sync. Push notifications, SMS or email updates at key delivery milestones are important to keep all parties informed. A lightweight web admin panel for user management, fare rules and basic analytics would round out the build.

Native or a high-performance cross-platform stack (Flutter, React Native or similar) is fine as long as the end result is fast, reliable and App Store / Play Store ready. Clean, modern UI that reflects our brand and works just as well on a phone held in one hand is essential.

If this scope aligns with your skill set let’s discuss timelines, recommended architecture and any questions you have about operational flow before we kick off.

Ideally: Developers stay with us for further developments (other projects on the shelf) and shared income

Please also mention the time you think you need to make an app like this.
