Shopify E-Commerce Store Build

I need a full-featured Shopify site that can start selling my physical products smoothly and securely. The project covers everything from choosing a conversion-focused theme and configuring the store settings to integrating payment and shipping, optimizing product pages for SEO, and ensuring the checkout is frictionless on desktop and mobile.

Please include:
• Customizable, responsive theme setup
• Collection and product page creation with variants, imagery, and clear pricing
• Payment gateway and real-time shipping integration suitable for physical goods
• Basic on-page SEO and speed optimization
• Launch support and a quick hand-over session so I understand how to manage orders, inventory, and promotions inside Shopify , load all the product into the digital store and descriptions etc

Successful delivery means the store is live, transactional, and I’m comfortable maintaining it myself.
