Recreate E-Commerce Website

I have an existing reference site that captures the exact look, flow, and functionality I want. Your task is to rebuild that experience for my own brand, keeping the focus on a smooth shopping journey.

Core requirements
• E-commerce structure that mirrors the example site, with clean Product listing and categorization so shoppers can browse by type, collection, and search without friction.
• Seamless Payment gateway integration using PayPal for both desktop and mobile checkouts.
• All pages responsive, fast-loading, and easy for me to update afterward (products, prices, images, text).

I will supply the example URL, brand assets, and product data as soon as we start. Please let me know which tech stack you propose, how you will migrate the design elements, and the timeline you need to launch a fully functional, test-ready site.
