Shopify Store Completion & Launch

My Shopify build is halfway there and I’d like an experienced hand to take it through to a polished, launch-ready state. The theme has already been chosen—I’ll share the exact name and a download link as soon as we start—so the job centres on applying that theme cleanly, tailoring the layout to fit my brand aesthetic, and making sure every page feels cohesive on desktop and mobile. What still needs doing: • Design & layout customization – adapt the chosen theme’s sections, typography, colour palette and imagery so the storefront looks unique yet stays on-brand. • Product listings – add products with photos; I need them imported, organised into collections, and given clear, conversion-focused descriptions. • Payment gateway integration – enable Shopify Payments, run a test transaction, and confirm all checkout workflows function smoothly. When the above is finished I’d like a quick pre-launch sweep: check speed scores, verify mobile responsiveness, and make sure essential SEO settings (titles, meta descriptions, alt tags) are in place. If you’ve taken partially built Shopify sites over the finish line before, this should feel straightforward. I’m ready to supply theme files, product data, brand assets and prompt feedback so we can wrap things up efficiently and get the store live.
