MadaTease Travel Mobile App Development

Hello, I'm looking to develop a mobile application for my Madagascar travel business, MadaTease (www.madatease.com). The website is currently being developed using WordPress by a separate developer. I want a mobile application for both iPhone and Android that connects to the existing website. The application should include: 1. **Tour Packages:** Customers can browse Essential, Comfort, and Luxury tours, including itineraries, prices, photos, and inclusions. 2. **Airport Transfers:** Customers can request airport pickups, drop-offs, and private transportation. 3. **Day Trips:** Customers can browse and request shorter excursions and local experiences. 4. **Booking Inquiries:** Customers select their preferred dates, number of travelers, and services. All bookings require MadaTease approval before confirmation. 5. **Booking Status:** Customers can view whether their booking is pending, quoted, confirmed, completed, or cancelled. 6. **Notifications:** Customers receive updates when their booking status changes. 7. **Customer Accounts:** Customers can view their inquiries and confirmed bookings. 8. **Contact:** Customers can communicate with MadaTease through the app. 9. **Website Integration:** The app must synchronize tour packages, pricing, customer information, and booking requests with the existing WordPress website. 10. **Private Driver Management:** Driver assignments and availability will be managed privately through the WordPress admin dashboard. Customers must not see or select individual drivers. I would prefer one shared booking system for both the website and mobile application, rather than separate databases. Please let me know your recommended development approach, estimated timeline, and total cost for building and publishing the application on both app stores. Thank you!
