Okay, I can help you start building a more professional and appealing version of that website using HTML, CSS, and JavaScript. We'll begin by setting up the basic structure and styling for the header and a hero section.

This sets up the basic HTML structure with placeholders for content, includes Font Awesome for icons, and provides initial CSS for layout, header, hero section, and footer. We've also added a basic script.js file for future interactivity like the mobile menu.

Next, we can focus on populating the content sections (About Us, Services, Contact Us) and refining the styling.
