Shopify E-Commerce Store Build

I need a complete e-commerce website built on Shopify. The goal is to launch an online store that looks professional, loads quickly, and makes it easy for customers to browse products, add them to the cart, and check out without friction. Because I’ve chosen Shopify, I’d like you to handle everything from theme selection or customization to app integration, payment gateway setup, basic SEO settings, and any tweaks that ensure the storefront is fully responsive on mobile and desktop.

I will supply product details, images, and branding assets as soon as we get started, but I rely on your guidance for optimal store architecture, collections, and navigation. Once the build is finished, I want a brief walkthrough so I can manage inventory, run promotions, and generate basic reports myself.

Please share relevant Shopify projects you have completed and let me know approximately how long you’ll need to deliver a launch-ready store.
