Products Selling Theme or Plugin

Hello everyone, am developing a WP site to help people sell their products online. Sellers will add their products with details like Product Title, Description and Product Images. Also the seller will add their contact details. The products will then be displayed on the Home Page as Ads. Buyers will view the products and contact the sellers for them to buy.

Is there a plugin or premium WP Theme that has these features, anyone who knows such a plugin or theme kindly assist me. Thanks.
