Editor or plugin Listing Category pages

Hi

I am creating a local market directory where vendors will be able to create listings to promote them self.

Example: The “Hazel Food Market” will be a listing category and “Johns meat” will be a vendor and create a listing.

The idea is to at least edit the listing category with some info on the market with images, description and contact details etc but I can not find a plugin for this. At the moment I am creating it in posts using column tags and then copy past to the listing category editor. It does work but not very responsive on mobile devices

Can someone recommend a plugin or alternative?
