Ride Hailing App Quote

I need a full-stack team to scope, design, and build a ride-hailing solution that offers an experience on par with Bolt or Uber. The product must launch simultaneously on both iOS and Android and feel entirely native on each platform.

Core feature set
• Real-time GPS tracking for riders and drivers
• In-app payments (major cards, Apple Pay / Google Pay, and wallet balance)
• Rating & reviews system for both parties

Advanced ride scheduling is desirable but not mandatory, so please show how it would affect price and timeline if included or left out.

Please outline:
• High-level architecture (mobile apps, backend, admin console)
• Your preferred tech stack and any licensing costs
• Milestone plan with estimated hours or story points
• Post-launch support options

I’m looking for a transparent, itemised quote that makes it easy for me to compare fixed-price versus time-and-materials approaches. Let me know if additional details are needed to lock down the estimate.
