I need a complete, dual-site solution under the single TopPicks domain: • TopPicks Furniture – a full-scale e-commerce storefront with a smooth cart, secure checkout, customer reviews and ratings, and advanced product filtering so visitors can quickly drill down by size, finish, or price. • TopPicks Booking – a property listing and reservation hub where owners can publish spaces, manage availability, and accept bookings through the same account they use for the shop. Both arms must share one login, a unified design system, and a friction-free switch between “Shop” and “Book” so users feel they’re still on the same site. Mobile responsiveness, lightning-fast page loads, and SEO-friendly architecture are non-negotiable. I’m open on the tech stack; WordPress + WooCommerce, a headless React front-end with a Laravel or Node back-end, or another modern approach—use what lets you deliver an elegant UI, clean code, and easy future scaling. Please outline: 1. Proposed architecture and key plugins/modules 2. Timeline with major milestones (design mock-ups, staging build, QA, launch) 3. Post-launch support and hand-off plan, including documentation Final deliverables are the two live sites, fully tested, connected to secure payment gateways, and deployed on my hosting, along with all source files and instructions for routine admin tasks.
