Folt: Innovative Ride-hailing iOS/Android App

I'm looking for an experienced app developer to build a ride-hailing app similar to Bolt or Uber, called Folt.

What the app must do:
- Sign up and log in with email and with Google
- Two user types: passenger and driver
- Passenger: enter pickup and destination, see the price, request a ride, track the driver on the map
- Driver: receive ride requests, accept or decline, navigate to the passenger
- Online payments (iDEAL, credit card, Apple/Google Pay), for example via Stripe or Mollie
- Ride history and ratings
- Simple admin panel to view users and rides

Technical:
- Platform: iOS and Android (preferably Flutter or React Native)
- Google Maps for location and routing
- App languages: Dutch and English

What I'd like to know from you:
- Have you built a similar app before? Please share examples or links.
- What is your timeline and fixed price, split into milestones?
- Which features do you recommend for a first version (MVP), and what can wait until later?
- I will own the code and the App Store and Google Play accounts.
