Professional and Responsive Webflow Landing Page for Mobile App Launch

We are seeking an experienced freelancer to design and develop a professional, high-converting landing page using Webflow. The primary goal of this landing page is to effectively capture leads for an upcoming mobile app launch. The design should be clean, modern, and fully optimized for responsiveness across all devices, including mobile and desktop.

Key sections to be included on the landing page are:
- A compelling hero banner
- Detailed features section highlighting app benefits
- High-quality app screenshots
- Testimonials from early users or beta testers
- A functional contact form for lead collection

The contact form must be integrated with Mailchimp or a similar email marketing tool to ensure seamless lead capture and management. The project is expected to be completed within a four-week timeframe, and we will require two rounds of revisions to ensure the final product meets our expectations.
