Flutter Vehicle Parking App Development

I'm looking for an experienced Flutter developer to create a comprehensive vehicle parking app. The app should cater to two main user roles: drivers and parking lot owners.

For drivers, the app needs to include:
- Real-time parking space availability: Drivers should be able to see which parking spaces are available at any given moment.
- Booking and payment system: An integrated system that allows drivers to book and pay for parking spots directly through the app.

For parking lot owners, the app should feature:
- Space management: Owners need to manage their parking spaces, including adding, removing, and updating availability.
- Payment tracking: A system to track all payments made for the parking spaces.

The ideal candidate should have:
- Proven experience in developing apps using Flutter.
- Strong understanding of real-time data handling.
- Experience with integrating secure payment systems.
- Good UI/UX design skills to ensure the app is user-friendly.

Please provide examples of similar work done. Looking forward to your proposals!
