Responsive Service-Based E-Commerce Website Build

I need a fully responsive e-commerce website built around selling services rather than physical products. The site should let visitors browse the different service packages I offer, add them to a cart, and pay securely without friction—no matter whether they’re on a phone, tablet, or desktop.

Key expectations
• Modern, mobile-first design that adjusts elegantly to any screen size
• Clean service catalogue pages where I can outline what each package includes, pricing tiers, and turnaround times
• Streamlined checkout with the usual e-commerce essentials: secure payment gateway integration, order confirmation emails, tax and fee calculations, and the ability for me to track orders in an admin dashboard
• Simple CMS or backend panel so I can create, edit, or retire service listings on my own after launch
• Solid SEO foundations (metadata, structured headings, fast load speeds) to help potential clients find the site organically

Tech stack is your call—whether that’s Shopify, WooCommerce, Next.js with a headless CMS, or something comparable—as long as it stays lightweight and easy for me to manage. If you have a preferred toolkit for service-based commerce, mention why you like it and how it would fit my goals.

Please include examples of similar service-driven e-commerce builds you’ve completed, plus a rough timeline for design, development, testing, and launch.
