Searching a web platform for creating an online flea market

[Kurzer]

Hello,

does anyone know a platform or an installable webshop that can be used to create a rudimentary online flea market (garage sale platform)?

It is supposed to enable a limited group (in this case the inhabitants of a city) to exchange "flea market articles" to give away or to sell for a little amount.

The participants should be able to place ads on their own, ideally with pictures, various categories and a validity period for the ad.

Kind of like Ebay classifieds. It doesn't have to be so extensive and sophisticated. I would prefer it to be hosted on my own server.
