Interactive Civil Engineering Website

I need an interactive web presence that not only presents my civil-engineering expertise in building design and 3D rendering but also gives visitors real-time ways to connect, explore past projects, and start new ones with me directly from the site. Key interactive elements to build: • Live chat support that works smoothly on desktop and mobile, so prospects can reach me instantly. • Virtual tours of selected projects—think 360° walkthroughs or embedded 3D models—so clients can experience the quality of my work. • A secure client project-management portal where each client can log in, view milestones, exchange files, and track progress. Client-input functionality: • Project requirements submission form that lets users upload drawings, photos, or briefings and choose service options. • Custom quote generator that pulls data from the submission and returns an estimated fee range on the spot. • Feedback and review system so completed-project clients can rate my service and leave testimonials. The finished site must be: • Fully responsive and optimized for speed. • Easy for me to update—preferably through a familiar CMS or clear hand-off documentation. • Integrated with analytics to track user behaviour and conversion. • Ready for HTTPS launch on my chosen host. Deliver everything from design mock-ups and source files to a live, tested site. Once it meets the criteria above and I can manage content myself, the project will be considered complete. i have exiting domain for the same
