custom configuration facebook connect on wordpress

I currently have the SFC simple facebook connect installed and set up on my site. The platform is wordpress. I would like to customize it so that when a user registers using facebook, a message is posted to their friend's walls on Facebook which says" ex. I just signed up at www.mywebsite.com. the post must also have a thumbnail image and a hyperlink to my homepage. This is not an experiment. This is not a test. I need this done properly. Please do not bid if you have not done this exact job before. In order to be considered for the job, you must send me a link to a similar completed job. thankyou
