Build Modern Clean Shopify Store

I need a full Shopify store set up from the ground up with a modern, clean aesthetic. Every page—from homepage to checkout—should feel streamlined and professional, reflecting a premium brand image.

Core requirements
• Customizable product options: shoppers must be able to choose variants or configure items (e.g., size, color, engraving) directly on the product page. Please implement this natively with Shopify Liquid or suggest a well-supported app if advanced logic is needed.
• Multi-currency support: the site should automatically display prices in a visitor’s local currency and allow seamless checkout without disrupting existing payment gateways.

Beyond those two features, I expect responsive layouts, fast load times, basic on-page SEO, and smooth integration with standard Shopify analytics and email marketing tools. I’ll provide product data and brand assets; you handle theme selection/customization, app setup, and any code tweaks (HTML, CSS, Liquid, JavaScript) required to make everything work flawlessly.

Deliverables
• Live, fully configured Shopify store adhering to the design brief
• Documented steps to add new products with custom options
• Testing proof for at least three currencies and major devices/browsers
• One revision round after initial hand-off
• Short hand-over video or PDF explaining key admin tasks

Please outline your approach, timeline, and any similar Shopify builds you’ve completed.
