Mobile Feature Showcase Landing Page

I’m looking for a fast, mobile-first landing page whose sole job is to showcase my new product’s features in a modern, clean style. I already have a loose color palette and a couple of wireframes, but I’d like your creative eye to refine them so the page feels polished and unmistakably on-brand.

Here’s what I need delivered:

• Hero banner with a clear headline, sub-headline, and primary call-to-action
• About section that tells the short story behind the product
• Feature highlights laid out in an easy-scan format (cards, icons, or similar)
• Testimonials carousel or grid for social proof
• Lightweight contact form that sends leads straight to my email (or Mailchimp, if you prefer)

Build it with lean HTML5/CSS3 and just enough JavaScript for interactions—Tailwind or Bootstrap is fine as long as page weight stays low and Google PageSpeed scores 90 + on mobile. The layout must be fully responsive down to 320 px wide, and the finished page should load in under three seconds on a 4G connection.

Please include at least two links to similar landing pages you’ve created so I can see your design sensibility and code quality. Also let me know your timeline and anything you’ll need from me to start.
