Responsive WooCommerce Store Build

I’m ready to launch a fully responsive e-commerce site and have chosen WooCommerce as the backbone. The store must feel fast and intuitive on any device, so mobile-first styling is a priority.

Core functionality I need in place:
• Robust product search with granular filters so shoppers can drill down quickly.
• A smooth, reliable shopping cart that keeps items cached between sessions.
• Secure payment-gateway integration (Stripe and PayPal are my preferred starting points, but I’m open to additional gateways you recommend).

Beyond those pillars, I’d like your help selecting and configuring the right theme, fine-tuning performance, and hardening security. Clean code, SEO-friendly structure, and thoughtful UX details (clear calls-to-action, quick-view, mini-cart, etc.) will be the markers of success.

Please outline how you’ll tackle setup, customisation, and launch, plus any plugins or custom snippets you see as essential. A concise milestone plan and example stores you’ve built on WooCommerce will make your proposal stand out.
