Need Simple Plugin That lists local stuff for sale?

I am looking for a simple plugin for an older gentleman that wants a website to sell local stuff kinda like an online garage sale for the local town people, no shipping or shopping carts kinda like cregslist
only real small scale. maybe something that he can list the stuff for sale item, price maybe a place for a picture of the item. Something real
east for him to add items and edit, hes, 70 years old and I don’t think he is very computer savvy. I’m a web designer/developer and this is kind of a Pro Bono thing.And I haven’t used WordPress extensively myself.
Anybody know of a plugin that might work for this? Or could I code a table in the editor that he could reuse without messing up the HTML?

Any suggestions would be greatly appreciated
