Marketplace Classifieds With Messaging

I need a full-featured classified website focused on straightforward buying and selling. Visitors should be able to browse and post listings in three core categories—Electronics, Furniture and Clothing—then communicate and close the deal without ever leaving the platform. Core functions I must see live: • Item posting with price, photos and category selection (electronics, furniture or clothing only). The website to have more category and is very similar to craigslist • Internal messaging so buyers and sellers can negotiate privately. • A rating & review system tied to each successful transaction to build trust and surface reliable sellers. Basic sign-up/login is of course necessary to power messaging and the review flow, but I’m not looking for elaborate public profile pages; keep it minimal. The finished site should be responsive, easy to navigate and ready for me to add more categories later if I choose. Hand-over must include source code, simple deployment instructions and a quick walkthrough of how I can manage listings and moderate reviews from an admin area.
