Customer-Enquiry Listing Website

I’m building a responsive marketplace where visitors who create a free account can publish product or service listings and potential customers can engage with them directly.

Core workflow
• Account creation unlocks the “Post a Listing” area.
• A listing form captures the exact fields I need—title, description, photos, price, location and the seller’s contact details.
• Shoppers browsing any listing can either send an instant enquiry through an on-site form or reveal the seller’s contact information to reach out off-platform.
• Every enquiry is stored in the seller’s dashboard for quick follow-up.

What I expect from the build
1. Modern, mobile-first frontend with intuitive navigation and search.
2. Secure user registration / login.
3. Listing management dashboard for sellers (create, edit, pause, delete).
4. Enquiry system that ties the message to the specific listing and notifies the seller.
5. Admin panel for me to moderate listings, manage users and view aggregated enquiry stats.
6. Clean database architecture that can scale as inventory grows.

Important: Please share your complete requirements clearly and step by step. This will help us develop the website according to your exact expectations and avoid missing any important functionality.
