Taxi Booking App (ios and android) and a Windows based management tool

Looking for someone to create a functional app for a small Taxi company. This app will be used in a small country. Some of the features would be similar to uber, but we dont need active GPS tracking or in-app payments as it will be mostly cash based (Consists of two apps: ) 1. A Windows based app (mothership) that an admin person can use in the office; and 2. A mobile app (ios/android) that customers will use to book a taxi ride. Drivers will also login to the driver portal section of the app and remain 'active' during their shifts, and can go 'on shift' anytime. Windows app: 1. Should be built in Visual Studio 2022 (.Net Framework 4.8, using VB.NET) 2. Provides a simple interface for office admin to see all customer data (name, address, phone, bookings) 3. Customer data exists in MS SQL Express databse hosted on Google Cloud (on a small Compute Engine instance, to minimize cost and stay within limits when possible) 4. Also provides a 'calendar' section where bookings can be viewed at a glance - And shows which drivers are 'online' (logged into the app and started their shift by toggling a button) 5. Also provides a 'manage drivers' section where new drivers can be added, and assigned user credentials(username/password) - and ability to view all their past/current bookings - and assign them to a specific 'region' - and view their last login date, type of phone they are using Mobile app: (ios and android) 1. Should be built in Visual Studio 2022 (.NET Maui, C#) - with a simple xaml layout that can be tweaked later. 2. Registered drivers, and any customer can login to the app: - 'login' screen shows 3 options (driver login, customer login, register) REGISTERED DRIVERS: - They login with the ID and password provided by the admin staff - Must have location services enabled on device (for google maps integration, distance calculation, etc) - Their personal details are pulled from the MS SQL cloud database and displayed in the app/can be edited - They can change their region (from the database list of available regions), add a photo avatar, change their display name the customer will see, etc. - Once signed into the app, they can toggle a 'start shift' button which sets an 'available' flag in the database CUSTOMERS: - They register for access to the app, providing: (email address, region, home address, phone, gender) - Use a simple text-message verification process to confirm new customer registrations. Then save data to the hosted database - Give the option to set a 'default' pickup address (but for each booking they can choose default, different address, etc.) - Option to create NEW PICKUP: - enter destination address, choose originating address - choose desired time (pickup NOW or later) - choose if the pickup is for themself or for a different person - they select from a list of available drivers in their region - show confirmation of details, and send the request to the driver. DRIVER receives the request (process) - 'incoming request' message pops up on their screen, showing the details - they can 'accept' the request, and enter an approximate arrival time (optional) - they have 5 minutes to accept the request. if no response is received, send the request to the next available driver in the customer's region REQUEST Accepted: - When a driver accepts a request, they see a message 'driver (name) has accepted your request, and is on the way' etc. - Show approximate distance of the driver (using google maps) - in database: record the distance at the time of acceptance, and customer request time etc - in database: mark driver as 'on route' When DRIVER is nearby (5-10 km away) - Notify customer driver is on his way (using push notification) - Show last known location on the maps (For simplicity we dont need to show a moving map of the driver's progress) - in database: record that the 'nearby' notification was sent, time, etc When customer is picked up - provide a way for the driver to indicate he has picked up the customer and on the way to the destination - in database: record that the customer was picked up, time etc When customer is dropped off: - Driver must check a box in the app when the customer is dropped off CUSTOMERS - If no driver is available, OR if they want to schedule for a later time or day: - On booking screen, give the option to setup a future booking - Enter date/time/origin/destination. - these get stored in the database so admin office user can assign a driver manually (depending on how far in the future the booking is for) - if less than 1 day away, put it in a 'queue' that can cycle between each driver (1 hour prior to pickup) until it's accepted - when accepted or assigned, customer gets an email and notification in the app to let them know their booking is scheduled.
