UK Electronics E-Commerce Website Build

I need a full-featured online store that sells a wide range of electronics to customers throughout the UK. The overall look should be corporate and professional, responsive on all devices, and quick to load.

Core storefront requirements
• Intuitive navigation with clearly defined product categories—laptops, TVs, gaming gear, accessories—while giving special prominence to Phones and Accessories on the homepage.
• Robust product search and layered filters so visitors can drill down by brand, spec, or price.
• Detailed product pages that support high-resolution images, zoom, and rich descriptions.

Checkout & payments
Security is paramount. The site must support multiple payment methods (credit/debit cards, PayPal, Apple Pay, etc.) through a PCI-compliant gateway, and display UK-wide shipping options—including delivery times and costs—before the customer commits.

Customer accounts
Registered shoppers should be able to log in to view real-time order tracking and a full purchase history. If your chosen platform offers extensions for wish-lists or loyalty points, note that, but these are nice-to-haves rather than requirements.

Admin & backend
Please set up an easy-to-use CMS so I can add or edit products, manage stock, and trigger shipping labels without touching code. Automatic tax calculation for UK VAT is essential.

Timeline & hand-off
Deliver a fully tested site (desktop & mobile) along with documentation showing me how to:
1. Add new products and categories.
2. Issue refunds or partial refunds.
3. Update shipping rates and promotional codes.

Feel free to propose the platform—Shopify, WooCommerce, Magento, or another—as long as it meets the feature set above and scales smoothly. Let me know your proposed tech stack, any premium themes or plugins you recommend, and the milestones you suggest for design, development, QA, and launch.
