Responsive E-Commerce Site Development

I want an end-to-end e-commerce website built with HTML, CSS, JavaScript, PHP, and MySQL. The look should be clean and modern, the layout fully responsive so it feels native on phones, tablets, and desktops alike.

Purpose
The site’s core function is to sell products or services online. That means the typical storefront flow must be in place—catalog browsing, cart management, secure checkout, and post-purchase order visibility.

Key customer-facing features
• Browse products or services and place orders
• Pay online using a payment method (integrate a mainstream gateway of your choice—Stripe, PayPal, or similar)
• Track orders and view purchase history through a personal dashboard

Core functionality to build
– User registration and login with best-practice security (hashed passwords, session handling, basic GDPR-friendly data storage)
– MySQL schema to store users, products, orders, and payment details references
– Admin dashboard where I can add/edit products, update order statuses, view sales metrics, and manage users
– Clear, intuitive UI so both shoppers and admins can navigate without a manual

Technical expectations
Clean, component-based HTML and CSS, minimal but readable JavaScript on the front end, and structured PHP on the back end. I’d like code that is commented well enough for another developer to follow. Please ensure mobile-first breakpoints and test across the latest versions of Chrome, Firefox, Safari, and Edge.

Deliverables
1. Source code (front end, back end, and SQL dump)
2. A short README explaining local setup, environment variables, and deployment steps
3. Deployed demo on a staging URL for review
4. Two weeks of post-handover bug-fix support

Timeline is important to me, so include an honest estimate for each milestone when you reply. Let me know if any requirement is unclear, and I’ll clarify quickly.
