Premium Ecommerce Site Build

I already own the domain and have a detailed PDF wire-frame ready; now I need the full site produced within an 8–10 hour window. The build must be a custom solution rather than WordPress, Shopify, or any other off-the-shelf stack.

Key requirements
• A polished, high-end UI that mirrors the layout in my PDF draft, but would be open to suggestions.
• Secure payment system fully integrated and tested.
• Real-time AI live-chat support widget.
. Would only be for 2-3 products initially, but would look to expand product range.
• Dedicated blog section with several starter posts formatted for on-page SEO, schema, and clean URLs.
• Overall site structured for strong technical SEO (fast load, semantic tags, meta data, XML sitemap).
• Mobile-first responsiveness and cross-browser consistency.
• Hand-off of deployable code and brief instructions for future content edits.

Please include links to previous ecommerce work showcasing similar advanced features so I can assess design quality and performance. I’m ready to provide hosting access, brand assets, and the PDF the moment we agree, and I expect rapid, communication-driven progress to hit the same-day completion target.
