There's multiple ways to do it:
* The SCSocialWidget Module configured as Facebook -> Like. In there, set the URL as whatever page you want the Like to be for.
* Use the Like tag: {JFBCLike href=http://facebook.com/sourcecoast}
Additionally, you may want to consider using the Like-Box SCSocialWidget, which is a Like button specifically for Pages. It can show the Like button, stream and user avatars for your page.
I hope that helps, but if not, or you have any other questions, just let me know.
Thanks,
Alex
