Php/css/wordpress Project

I have a wordpress blog and I am looking for a very small, specific feature on my blog. I want to include the Facebook like, Retweet button, and Google Buzz buttons in my post header (like they have at http://techcrunch.com/). I already have the Retweet and the Google Buzz buttons, I just want you to include Facebook like button and ensure that the formatting is correct.

Make a reasonable bid, looking to close this ASAP.
