VehicleInfo Clone for Android & iOS

I need a full-feature replica of the VehicleInfo app (https://play.google.com/store/apps/details?id=com.vehicle.rto.vahan.status.information.register) built natively for Android and iOS. The core modules must match the original—vehicle information and history lookup, challan enquiry and payment, FASTag recharge, insurance purchase, and RC-related services—while adding push notifications for service reminders and clean hooks for future third-party integrations.

The UI should feel professional and formal, consistent across both platforms. I am open to your preferred tech stack as long as it guarantees smooth performance, secure data handling, and straightforward maintenance; please justify your choices.

When you respond, include:
• a realistic, itemised cost for end-to-end development (no placeholder ranges)
• a clear timeline with major milestones until the apps are live in both stores
• a brief outline of the architecture and tools you propose
• links to any comparable mobility, finance, or utility apps you have shipped

I’m ready to move ahead ASAP, so the more detail you provide up front, the faster we can lock the scope and start.
