Corporate Website Clone & Refresh

I need my existing corporate website duplicated on a fresh code-base and given a complete visual overhaul. The goal is to keep all current pages, links, and overall structure intact while delivering a modern, responsive design that reflects our brand more effectively. From the homepage through every inner page—About Us, Services, Contact, careers, resources, the works—I want everything rebuilt so the content migrates seamlessly but looks and feels new.

Please handle:
• Full site cloning (HTML / CSS / JS or CMS export)
• Pixel-perfect redesign with mobile responsiveness and fast load times
• Smooth migration of all copy, images, and embedded assets
• Basic on-page SEO retained (meta tags, alt text, headings)

I’m open to your recommended stack or theme so long as maintenance remains straightforward for our in-house team. Deliver the finished site on a staging server for review; once approved, push it live and supply the source files.
