Urgent Website Redesign Rebuild | Long Term Freelancer Required Experience

My current site needs a full rebuild with an updated, modern design that loads fast, looks great on every device, and keeps visitors engaged. The chief objective is to refresh the visual style—layout, typography, colour palette, imagery, and overall user flow—while preserving all existing content and functionality.

Speed matters: I’d like to see first mock-ups immediately and the finished, migrated site live as soon as possible. A smooth hand-over is essential so there is zero downtime during the switch.

When you reply, focus on your experience tackling similar redesign projects. Point me to live sites you rebuilt, outline the tools or frameworks you prefer (WordPress, React, Webflow, custom CSS, etc.), and briefly explain how you keep SEO and performance intact during a redesign. That proven track record will carry more weight than lengthy proposals.
