Custom Service Sales Website Build

I need a clean, conversion-focused website that lets me present and sell my custom services directly online. Visitors should be able to browse service options, submit the details I request, and complete payment in one streamlined flow.

Core needs
• Modern, responsive design that carries my brand style.
• Clear service pages where I can outline deliverables, turnaround time, and pricing tiers.
• Secure checkout with major card support (Stripe or similar) and automated receipts.
• Dashboard or CMS so I can add new custom service offerings, adjust pricing, and view orders without touching code.
• Basic SEO set-up so the site is discoverable from day one.

Preferred stack is flexible—WordPress with WooCommerce, Shopify, or a lightweight custom build are all fine as long as the final result is stable, easy for me to maintain, and scales with more services later.

Please share a quick outline of how you’d tackle the build, the tools you’d use, and a realistic timeline for first launch.
