Shopify Store Design Revamp

I’m looking for a Shopify developer who can give my store a fresh, cohesive look and feel. My main objective is to improve the overall site design so that every page guides shoppers smoothly from discovery to checkout.

Scope of work
• Re-work the homepage layout to make the value proposition instantly clear and visually appealing.
• Refresh product-detail pages so images, descriptions, and calls-to-action sit in a clean, mobile-friendly layout.
• Streamline navigation, collection pages, and the cart for faster path-to-purchase.
• Apply a consistent color scheme and typography across the theme.
• Adjust underlying layout and section structure where needed in Liquid, CSS, and theme settings.

Deliverables
1. Design mock-ups or live previews for the updated pages.
2. Theme code adjustments (Liquid, HTML, CSS, JavaScript) implemented in a development copy of the store.
3. Testing on desktop and major mobile breakpoints to ensure responsiveness and speed.
4. A short hand-off document summarizing changes, so I can manage minor tweaks later.

I already have an active Shopify store; you’ll have collaborator access and can start right away. Please share relevant Shopify design examples and let me know your estimated timeline for this medium-sized revamp.
