Cross-Platform Parking Mobile App Development

I'm looking to build a mobile app for both iOS and Android platforms. The main aim of this app is to assist users in finding parking spots.

Key Features:
- Real-time Availability: The app should display real-time information about available parking spaces.
- Payment Integration: Users should be able to pay for their parking directly through the app.
- Navigation to Parking Spot: The app should provide directions to the selected parking spot.

Ideal Skills:
- Cross-platform Mobile App Development
- Expertise in real-time data handling
- Experience with payment gateway integration
- Navigation and mapping software familiarity
