how do I set up a Facebook page for my business?

[Erik B]

I already have a "Like" button on my website which I am the administer for in Facebook. If someone searches for our business ("Republic Precious Metals Exchange") it takes them to our web site. I would like to turn this to an actual Facebook page where visitors can see previous posts, etc.

Also, there is a community page for us ("RPMEX") but there is not a link for "Is this your page" like there is for some other community pages. I wonder if Facebook has removed this option, or if a competitor has taken control of this community page.
Just to be clear, I know how to set up a Facebook page for my company. I've done it before, but I want to avoid creating a whole new page and losing my followers. I want to turn my existing page that administers the like on my website to an actual Facebook page. Another item that is weird is that if I go to our web page, the "like" box gives me a link to enter as an admin because I am an administrator. But when I go into my personal Facebook page and go to "Use Facebook as a page" I have no options there like I used to.

An example of what I am trying to do is http://www.artforcongress.com/ they have an actual Facebook page which is directly associated with their Facebook page, and not a separate page for each
I meant, a web site associated with their Facebook page.
