Innovation Management Associate | Business Development Consultant | Business Model Innovator
Your target should be getting traffic to your marketplace and making prospects actually decide to use your service. This of course is done with proper marketing as well as having the right business model.
Try having a mixed business model where you provide a free listing that is basic and then provide paid services that boost the listing and its chance for successful sale such as Pinned Listing. Moreover, monetize ad spaces within the marketplace pages.
