Subscription-Based Ride Sharing App Development

I'm looking for a seasoned developer or team to create an Uber-like app for both riders and drivers. Unlike traditional ride-sharing apps, this one will operate on a subscription basis. Here's the breakdown:

Core Functionalities:
- Ride Booking: The app should facilitate easy ride booking for subscribers.
- Subscription Management: Users should be able to select and manage their subscription plans seamlessly.
- Driver and Rider Profiles: There should be distinct and manageable profiles for both drivers and riders.

Additional Features:
- In-app Messaging: A secure and user-friendly messaging interface for drivers and riders.
- Ratings and Reviews: A feedback system to maintain service quality and accountability.
- Payment Gateway Integration: A reliable and secure payment system for subscription payments.

User Interface:
- Design: The app should have a modern and minimalistic design. Clean lines, ample white space and a limited color palette will be essential to create a user-friendly interface.

Ideal Skills:
- Proficiency in both iOS and Android app development is a must.
- Extensive experience in creating ride-sharing or similar apps.
- Strong UI/UX design skills, with a focus on minimalistic design.
- Expertise in integrating secure payment gateways.
- Experience in implementing in-app messaging and rating systems.
