Responsive WordPress Redesign

I’m ready to give my existing site a fresh start on WordPress and I need a partner who can take it from end-to-end. The look I’m after is modern and clean, with a layout that adapts perfectly to mobile, tablet, and desktop screens.

Here’s what the project involves:
• Migrate—or rebuild, if easier—on WordPress, setting up a flexible page structure so I can expand later without breaking navigation.
• Design and develop the core pages (Home, About Us, Contact Us) plus 5–7 additional sections such as Team and Clients, keeping the visual language consistent throughout.
• Install an SSL certificate, tighten security best practices, and tune loading speed (image compression, caching, and any other performance wins you recommend).
• Handle on-page SEO essentials: write or refine meta titles and descriptions, set proper heading hierarchy, and ensure clean URLs.

Please tell me:
1. Your approach to redesign versus rebuild.
2. Rough timeline and cost breakdown (milestones are fine).
3. Any recent WordPress work that shows a similarly modern, clean aesthetic.

I’m happy to answer questions about content or brand guidelines—let’s make this upgrade smooth and scalable.
