Simple Script or Plugin for WrodPress Site

I need a script or plugin that I can add to many pages of my WordPress site. I am designing a website and I need a form where people can post simple ads and have the results displayed on the same web page where the form is. The person should be able to have the ability to post for a period of one day and to upload 3 photos which would be shown in the post. I will be using the exact same form on many pages. This script/form would have to be integrated with WordPress member database so people can contact poster by a reply form with NO email address of the poster or person replying knowing anyone’s email address. The posts would have to expire and be removed automatically from the page after 24 hours. The person would also have the ability to edit their post. There should NOT be the ability to comment on a post directly. I know this is probably a simple form setup, but, I don’t have the time to do it. I can give you a screenshot of what I am aiming for. I’m hoping this is a simple plugin There should be a “flag post”. Example: [login to view URL]
