I need a fully operational e-commerce website set up on Shopify that is ready to start taking orders the moment we launch. The store must include robust product search and filtering so customers can quickly find what they need, individual user accounts for tracking orders and wish-lists, and a seamless, secure payment gateway integration covering all major cards and PayPal. Behind the scenes I want a clean admin dashboard where my team can add or edit products, view sales analytics, and manage inventory without touching code. All designs should be responsive and load fast on mobile as well as desktop. Please handle the full build: theme selection or custom theme work, configuration, minor design tweaks to keep branding consistent, and testing to be sure checkout, accounts, and search all work flawlessly. Once complete, handoff should include brief onboarding so we know how to run the store day-to-day.
