Required software development,Website Development freelancer for Need a browser extension for automation of single work job

I'm looking for a browser extension , preferably chrome which allows me as a retailer to post ads on our website. The thing is normally the site displays the results on top as per last posted and so many companies post the same ad multiple times. The process to post same ad again and again is I think best handled by an extension which will allow me to modify the ad and re post like a robot.
Its not much of a large project and so budget is restrictive.
