E-Commerce website

I need a fast, secure, and modern e-commerce website that lets customers purchase my professional services as smoothly as they would buy a product. The layout must follow a clean, modern design style and remain fully responsive across mobile, tablet, and desktop.

Core functions will include a searchable, category-driven catalog of services, detailed service pages with pricing and promotional options, a streamlined shopping cart, Razorpay payment processing, eKart delivery API (for any physical add-ons or document shipments), user registration, and a robust admin panel for managing everything from offerings to orders.

I also want these customer-facing extras clearly integrated:
• Live chat support
• Customer reviews and ratings
• Advanced filtering options

Please build with SEO best practices, solid security, and performance optimization in mind. On completion, I expect a fully deployed site, admin credentials, and short hand-over documentation so I can add or modify services without touching code. If you prefer a particular framework or CMS, let me know; I’m flexible as long as the final result is reliable, easy to maintain, and ready to scale.
