Facebook clean Like button in Magento Header

Hi, I have a shop [login to view URL] and I want to add a social plug in to allow people to click LIKE for the page I want it to be very cleanly and aesthetically installed and place like this one [login to view URL] I also have a pop up that comes up and I would like a clean Facebook like button installed into that pop up also. Again it must be very tasteful. Please I have no plans of paying too much for this, so do not bid silly quotes and please detail in your reply your plan for doing this and the time frame.
