High-Converting Landing Page Designer

I am looking for a high-level landing page designer to create a clean, premium, conversion-focused demo page for our AI voice agent.

This page has one goal which is to - Get users to interact with the AI demo (call the system)

What the page needs to do:
-Immediately communicate value (within 3 seconds)
-Drive users to click a “Call Now” CTA
-Feel premium, modern, and minimal
-Work perfectly on mobile and desktop

Page Sections:
-Hero section with strong messaging + CTA
-Click-to-call functionality
-Secondary link to demo website
-“What you’ll experience” section
-Features & benefits (outcome-focused, not generic)
-“What to say” guidance section
-Social proof / testimonials
-Secondary CTA (book a call)

Design Expectations:
-Clean, high-end SaaS feel
-Strong spacing and typography
-No clutter or long paragraphs
-Built for conversion, not aesthetics alone

We would like this built in GoHighLevel
