Modern Luxury E-Commerce Website

I want to launch an online store that feels as refined as the jewellery and handbags I sell. The aesthetic must be modern and minimalist—clean lines, generous white space, and subtle, sophisticated typography that lets each product shine without distraction.

Core requirements
• A full e-commerce build, not just a catalogue.
• Responsive design that looks flawless on phone, tablet, and desktop.
• Fast, intuitive navigation with clear product categories for jewellery and handbags.

Essential functionalities (must be fully implemented):
- Shopping cart and checkout
- User reviews and ratings
- Product search and filter

Smooth inventory management, secure payment integration, and SEO-friendly structure are expected parts of the build. I’m flexible on the underlying platform (Shopify, WooCommerce, Magento, or a custom solution) as long as it delivers a premium experience and can scale with future collections.

Please factor in basic training or concise documentation so I can update products and run promotions without developer intervention. A concise timeline, a portfolio of similarly high-end sites, and any initial design thoughts will help me choose the right partner.
