Add Facebook - Viral Video Script to my Video Sharing Web!

My Budget is: $75 USD Job will be paid when I see Demo Working. I need a Professional Freelancer, I need this script Nice and Easy. I will provide an image sample, how the script should work. MAIN GOAL: Get my website videos go viral on Facebook. I have a Video Sharing site. Videos come from YouTube. I want my visitors in order to watch the Video, They must share that Specific video Content on their facebook Wall with a Facebook App. Note: I need this script to works Clean and Professional. I don't want to make my visitors leave my website that easy. Is very important that this scripts go through a Facebook app, this way the App API will know if the user a ready share the same content before or not, if they did, they won't need to share that particular video content again in order so watch the video again. The Idea is, when visitor try see a video, To show a box with a background image (size 540x430) the same size of the Player. I will create a nice background image) at the middle of this box I want the Facebook Share Button, to see that particular video content right after they share the content, show the video to the visitor. My web site load the video with my script website, this peace of Code must be loaded in the same area where the box with the image background is locate, in other word, the box background will disappear, right after they share the video. Very important: Freelancer must show me a demo working I will give you a DEMO site, similar to the main site where the Script is going be install, so I can test the script. Once we test the script, it must be install in the main site. Note: Only Bid If you understand what I need.
