I need a complete e-commerce site built on Shopify. The work starts with theme selection or custom design, then moves on to configuring products, collections, taxes, shipping, and a secure checkout so the store is ready for real customers. All pages must load quickly, look polished on desktop and mobile, and be easy for me to update after launch. Please handle: • Initial store set-up and theme customisation • Integration of standard Shopify apps essential for smooth sales and basic marketing • Testing to be sure the entire purchasing flow—from product page to order confirmation—works flawlessly When the site is live and tested, hand over clear instructions or a brief video showing how I can add new products and run day-to-day operations.
