Complete E-Commerce Website Setup

I am launching an online store that will sell my own “Website Full Design & Setup” service and I need the entire e-commerce environment built from scratch. The look has to feel modern, uncluttered and professional, with a neutral-tone palette that remains consistent across desktop and mobile views.

Here is what I expect as final, working deliverables:

• Custom homepage, product and informational page designs matching a modern aesthetic in neutral colours
• Fully responsive layout tested on major desktop and mobile breakpoints
• One service-type product uploaded, with category structure in place so I can add more later
• Payment gateway configured for UPI, credit/debit cards and Cash-on-Delivery
• Shipping and delivery rules set up (rates, zones, order tracking ready)
• Privacy Policy, Returns, Shipping and Terms & Conditions pages drafted and linked in the footer
• Basic on-page SEO, image optimisation and speed tuning so the site loads quickly on 4G mobile
• WhatsApp click-to-chat and standard contact form integrated and tested

Please build on a platform that lets me manage products and content easily once you hand it over. A smooth, bug-free checkout flow and page-load speed under three seconds on Google PageSpeed Insights will be my key acceptance criteria.
