Mobile App for Car Cleaning Services

I want an application to be build for Android and IOS version of mobile for my business which is basically provides car cleaning services on regular basis. Once installed:

*Project goal*: Create a user-friendly app for booking car cleaning services in apartment complexes.

Scope of work:
- Develop a login system for users to create and access their accounts
- Implement functionality for users to select their society name, tower, and flat.
- Create a system for users to input car details like SUV or sedan.
- Provide package options based on car type for users to select.
- Assign car cleaners and display their check-in and check-out times.
- Enable feedback submission for completed cleaning services
- As an admin, I should be able to assign car cleaners if someone is absent and that should go as a notification to customers who are being served by that car cleaner that their regular cleaner is on leave and another cleaner whose photograph and name is this... Has been assigned
-Also as an admin I can see the feedbacks for my employees (car cleaners) and can respond to those feedbacks
- As an admin I can see who has opted for which package and if payment gateway is integrated then payment can be set as an auto payment.


Additional information: I want to keep it simple although but based on overall charges I want to see how much this is going to cost me. If it will be within my budget then I would like to add payment method process as in gateways to be added as well
