Zillow-Style Real Estate Platform

I’m looking for an experienced web developer/team to design and build a fully functional real estate platform similar to Zillow.

The platform should include core Zillow-style features such as:
• Property listings with advanced search & filters
• Interactive map-based search
• User accounts (buyers, renters, agents, admins)
• Property detail pages (photos, videos, pricing, history)
• Favorites, saved searches, and alerts
• Agent profiles & contact tools
• Admin dashboard for listings, users, and content management
• Responsive design (desktop & mobile)
• Scalable backend and secure database

The goal is feature parity with Zillow, not just UI — the site must be fully functional, performant, and production-ready.

Please include:
• Relevant past projects (real estate platforms preferred)
• Proposed tech stack
• Timeline and cost estimate
