Mobile app Mvp for appointment system

Looking to build MVP for a mobile app appointment system.
It will need to register business with verification and fill in service provided, charges and time for the service along with other business information.

Once the registration is completed it should appear on the app for user to book appointment for the service.
User will need to register to be able to book appointment.

Database should be managed and work properly.

Will need to start with the design and after finalizing it will move to app development.

Any ongoing feedback needs to be implemented as per requirements.

Will need to use different software api to build this system and make it work quicker
