I need a fresh, elegant web presence for my jewelry brand that not only showcases each piece beautifully but also allows customers to purchase directly online. The aesthetic is paramount—clean lines, refined typography, and a luxurious palette that reflects the craftsmanship behind every collection. Functionally, the site must cover three core areas: a welcoming Home Page that introduces the brand story, an easy-to-browse Product Catalog with rich imagery and filters, and a straightforward Contact Us page so clients can reach out for bespoke requests or support. E-commerce is essential, so the build should include a secure cart, checkout, and payment-gateway integration. I’m open to your recommendation on the ideal platform (Shopify, WooCommerce, or something comparable) as long as it supports responsive design and is simple for my team to update. Deliverables: • High-fidelity mock-ups for Home, Product Catalog, and Contact pages in the agreed elegant style • Fully responsive front-end and back-end implementation with complete e-commerce workflow (cart, checkout, payment gateway, order confirmation) • Basic SEO setup, speed optimization, and on-page security best practices • A short hand-off guide or video walk-through so we can add products and manage orders independently Please share relevant portfolio examples that demonstrate your ability to balance sophisticated design with seamless online shopping, along with an estimated timeline for each milestone.
