React + Next.js Twin Website Development

I need a developer to create two separate websites using React + Next.js (Version A and Version B).
Both will be stored in one GitHub repository.

I will provide two HTML files (white version + black version).
Your task is to rebuild both pages in Next.js with similar logic, a slightly modified design with an attractive look, and a similar structure.

In addition, I will provide a PHP file that will determine which option to display; it also needs to be integrated.

What you need to deliver:
• Two Next.js projects (Version A and Version B).
• One PHP file that chooses which version to display.
• Full project stored in one GitHub repo.
• Deployment setup (developer should propose a working hosting solution, because GitHub Pages does not run PHP).
• A short README with setup & deployment instructions.

Requirements:
• Strong React/Next.js skills
• PHP experience
• Ability to set up and connect Next.js + PHP
• Clean structure & readable code

Please include in your offer:
• Your experience with Next.js and PHP
• Your idea of how to host both Next.js builds + the PHP router
• Price & delivery time
