Responsive Corporate WordPress Site Build

I need a skilled WordPress developer to create a dynamic corporate website that feels modern, loads fast, and scales smoothly on any device. The build must rely on the native block editor (or a block-friendly visual builder) so that I can update content myself without touching code.

Core requirements
• Live chat fully integrated and styled to match the brand
• Mobile-first, responsive layout that looks perfect on phones, tablets, and desktops
• On-page SEO best practices baked in from the start—clean permalinks, lightweight theme, schema markup, meta tags, and WebP images
• Modular block-based pages so future sections can be added or rearranged easily

At hand-off I expect:
1. A secure WordPress installation on my hosting, with all theme, child-theme, and plugin files.
2. The complete site populated with sample corporate pages (Home, About, Services, News/Blog, Contact, products).
3. Live chat tested and working.
4. PageSpeed Insights scores in the green for both mobile and desktop.
5. A short video or PDF showing me how to update text, swap images, and manage the chat widget.

If this sounds like a build you can deliver, please share a link or two to similar corporate sites you have shipped.
