Simple Website Development Needed

I’m looking for someone who can take my initial idea and turn it into a functioning website from the ground up. Right now the concept is open-ended, so I’m happy to hear your recommendations on the best platform, structure, and technology stack.

Key points:
• Clean, modern layout that works smoothly on desktop and mobile
• Fast loading times and basic on-page SEO best practices baked in
• Room for expansion later—please set it up so adding new pages or features won’t require a rebuild

Deliverables:
1. Fully responsive website (live on my domain)
2. Brief hand-off guide explaining how I can update text and images on my own
3. Source files and any custom code stored in a shared Git repository

If you’ve built similar sites before, share a couple of links along with a short outline of the tools or frameworks you used. I’m ready to start as soon as I find the right fit.
