I have an html template. Setting it up is fairly easy as I know markup, JS and Jquery. But I am kind of weak on back end development. Anyway, I want to setup up an e-commerce where users can submit their own property to be included in the store. So far I have not found any luck finding a php plugin, api, app etc. I would like to find something out of the box.

If anyone can help me find lone I would be so happy. Thanks.
