Hotel Resort Booking Website Development

I need a modern, responsive website built for my hotel resort with a complete online room booking system.
​Key Requirements:
​Room & Property Showcase: High-resolution photo galleries, room categories, pricing, amenities, location map, and a contact/inquiry form.
​Online Booking Engine: Real-time room availability calendar, check-in/check-out date selector, guest count, and instant booking confirmation emails.
​Payment Gateway Integration: Secure credit and debit card checkout (e.g., Stripe, Razorpay, or PayPal) linked directly to my business bank account for automated payouts.
​Admin Dashboard: An easy-to-use backend where I can manage reservations, update room rates, block dates, and edit content without coding.
​Technical Basics: Mobile-friendly design, fast loading speed, SSL security, and basic SEO setup.
​Please share examples of hotel or booking websites you have built previously, along with your estimated timeline and recommended platform (e.g., WordPress with a booking plugin or custom build).
