Auto Feature Image - WordPress Plugin

Need a basic plugin that does the following: Automatically checks a certain post category's posts to see if they have a featured image. If no featured image is found, it will set one to one predefined in the settings. You should be able to create as many featured image audits as you want: Example: I want it to check category1 if a featured image is set. If no featured image is set, it will set it to image1. I want it to check category2 if a featured image is set. If no feature image is set, it will set it to image1. It should do the auto checking via cron job. ***NOTE*** - Do not copy/paste me your standard hire-me message. I will not choose you if you can't take the time to clearly communicate with me that you understand my specific needs. If I get a copy/pasted hire-me, you will be ignored.
