Travel Booking Website Development Needed

I run a travel company and now need a web presence that does more than showcase destinations—it must handle every step of the booking journey for hotels, tour packages and flights. The core requirement is a fully-functional reservation system with real-time availability, secure payments and automated confirmation emails.

I am comfortable combining an off-the-shelf theme or template for the basic layout with custom-built modules where unique logic is required, so feel free to recommend the best blend of WordPress, Shopify, Laravel, React, or any stack you believe fits both speed and scalability.

Key deliverables
• Responsive front-end pages for hotel, tour and flight searches, each with filters, pricing and calendar views
• A unified cart / checkout that accepts major cards and popular wallets, plus voucher or coupon codes
• Back-office dashboard where my team can add or edit listings, set inventory and pull sales reports
• Integration with email and WhatsApp for automated booking confirmations and reminders
• Basic SEO setup (metadata, sitemap) so new packages show up quickly on Google
• Launch support: migrate to my hosting, point the domain and run a live booking test

Please outline the tools or plugins you intend to use, estimated timeline, and any similar travel sites you’ve built so I can see your approach in action.
