Service Booking Site, Razorpay Integration

Job ID: 40603732

Budget: $30 – $250 USD

I’m setting up a small service-based website that will run between three and five pages. The core flow is simple:

• A visitor lands on the site, browses the services, then uses a built-in cost-estimation calculator to see an instant price.
• From there they choose a slot through a booking interface and pay securely via Razorpay.
• Once the order is confirmed, the Meta Business API should trigger an automated message (WhatsApp or Facebook) that recaps the booking and payment details.

What I need from you
1. Design and build a modern, mobile-first site (3–5 pages is enough for Home, Services, Calculator/Booking, About, and Contact).
2. Develop the cost-estimation calculator so I can adjust pricing or parameters later without digging into code.
3. Implement a streamlined booking module that captures date, time, and basic customer info, then passes that data to Razorpay at checkout.
4. Integrate Razorpay for full payment flow (order creation, callback handling, success/failure pages).
5. Connect the Meta Business API so every successful payment automatically triggers a confirmation message.
6. Handover must include all source files, a short admin guide, and a brief walkthrough call so I can maintain content or prices on my own.

Acceptance criteria
• Pages load fast (<3 s on 4G) and display flawlessly on mobile and desktop.
• Calculator returns the exact figure that Razorpay ultimately charges—no rounding surprises.
• Successful payments always trigger one Meta Business API message; failures never do.
• Code is clean, documented, and committed to my Git repo before final hand-over.
