486228 Wordpress Plugin _ Facebook _ Twitter _ Linkedin etc

I'm looking for a programmer that can build a plugin that posts out from the wordpress admin panel whenever someone publishes a post. It needs to allow for appropriate sized text boxes for custom publishing of content about the post to these social media sites or auto gen from the text of the post. (user selected) At it's core I need it to post out to Facebook (page or profile - user selects), Linkedin and Twitter Also would like some [login to view URL] functionality so that it could post out to a few other social sharing sites as well...either through [login to view URL] or directly via this plugin. Please only post if you've created wordpress plugins before and know how to make this happen. I don't want any "I think I can" type of quotes. Thanks in advance and I look forward to your quotes. .
