Welcome to the Q&A Forum

You have quite a bit of activity already on your Facebook page, so I would just link your website over to your profile. Also, I would suggest creating a Facebook specific conversion page on your website, and iframing it into a Facebook tab.  That way you can still collect contact info/email addresses to continue to market to people. I can't remember the exact size of the iframe, but its something like 520px wide, but the suggested size is 480px in order to fit a scroll bar in the window.
