Ad management system, wp to twitter plugin and google ads

This project involves 3 tasks. Please note that there will be more projects from us in the future if we get quality work from the developer. 1. Find out a suitable ad management system and install it in our site. The ad management software should be locally hosted. * The ad management system should be able to group together ads for different pages * Be able to track clicks and impressions and display monthly and ongoing statistics * Preferably written in PHP 2. Find out a way to push wordpress posts to twitter. We had used the wp plugin full circle before, but it stopped working. 3. Integrate google ads to wp sidebar and posts
