Service-Based WordPress Storefront

I’m launching an e-commerce site on WordPress that will sell professional services rather than physical or downloadable products. I already have hosting arranged; what I need now is a developer who can turn a clean, conversion-focused design into a fully functioning storefront.

Core requirements
• Build or customise a modern, responsive WordPress theme that presents each service as a product with clear descriptions, pricing and an “add to cart / book now” flow.
• Configure WooCommerce (or another proven plugin you prefer) so clients can choose a service, schedule it if necessary, and pay securely via Stripe, PayPal and credit card.
• Set up the essential pages: Home, Services catalogue, Individual service detail, Cart, Checkout, My Account, Contact, plus any policy pages.
• Optimise load speed, mobile experience and basic on-page SEO.
• Hand over a back-end that lets me add, edit or retire services easily.

Nice-to-have (let me know if you can include)
– Automatic invoice generation and email notifications
– Simple coupon system for promotions
– Integration with Google Analytics and Facebook Pixel

Acceptance criteria
1. I can list a new service myself, assign a price, publish it and see it appear correctly on the catalogue page.
2. A test purchase goes from cart to payment confirmation without errors.
3. The site scores 90+ on Google PageSpeed Insights (mobile).
4. All pages render properly on current versions of Chrome, Safari and Firefox, both desktop and mobile.

Please outline your approach, the plugins you’d rely on, and an estimated timeline.
