Gaming Top-Up Website Development

I want a lean, working web platform where players can instantly top-up Mobile Legends (MLBB) diamonds. The user flow is simple: the buyer enters their Player ID + Zone ID, selects a diamond bundle, pays through UPI, and then receives the diamonds once I approve the order in the back-end.

Key points I need covered
• Front end – clean, responsive pages that list diamond packages, capture in-game IDs, and show order status updates.
• Checkout – UPI is the only required payment method. A QR / deep-link generator with automatic payment confirmation is ideal; manual confirmation via the admin panel is acceptable if automation pushes cost too high.
• Admin area – secure login, pricing table, order list (filter + search), and a “mark as fulfilled” action that sends the buyer a confirmation message.
• Basic security essentials (HTTPS ready, CSRF protection) and straightforward UI/UX.

Deliverables
1. Full source code with a short deployment guide (shared hosting or VPS).
2. A live demo on my domain or subdomain so I can test end-to-end.
3. One revision round after my review.

My working budget is ₹2 000–₹5 000. Please outline exactly what you can include for that range and flag any third-party costs that might push it higher. If you have a ready-made template you can adapt quickly, tell me—speed and reliability matter more than elaborate graphics.
