Service-Based E-Commerce Website Build -- 2

I’m ready to launch a full-featured e-commerce site where visitors can purchase my service packages directly online. This isn’t a store for physical goods; every item in the catalog is a service—primarily website-related work such as design, implementation and ongoing support—so the flow must feel more like booking expertise than adding gadgets to a cart.

Scope of work
• Responsive front-end that reflects my visual brand and loads fast on mobile and desktop.
• A service catalog with clear package pages, optional add-ons and tiered pricing.
• Checkout built for intangible products: no shipping steps, just secure payment (Stripe or PayPal preferred) followed by instant confirmation e-mails.
• Simple dashboard where I can add new service offerings, edit copy and adjust prices without touching code.
• Integrations: contact form, basic analytics (Google Analytics 4) and an opt-in for my mailing list.
• SEO-friendly structure and on-page meta so I can rank for key “website services” terms.

Acceptance criteria
1. All core pages (Home, Services, About, Contact, Terms/Privacy) published and styled consistently.
2. Test order for a service processes end-to-end, payment captured and confirmation e-mail received.
3. PageSpeed Insights mobile score of 80+ on the live site.
4. Administrator login delivered with clear hand-off notes and a brief Loom walkthrough.

I’m open to WordPress + WooCommerce, Shopify, or another reliable platform—choose the one that gets the job done cleanly and keeps future maintenance straightforward. Please let me know which stack you recommend, why it fits a service-based store, and show a live example of something comparable you’ve built.
