Build MVP Marketplace for Construction Surplus Materials

I am looking for an experienced web developer to build a marketplace website that connects buyers and sellers of surplus construction materials. I currently facilitate these transactions manually and am looking to create a web-based platform that streamlines the process and allows it to scale. The primary objective is to build a practical and cost-effective MVP (Minimum Viable Product) that can be expanded in future phases. I am looking for recommendations on whether this should be built using WordPress, an existing marketplace framework, or custom development.
