From my Tools For Real Estate blog:
A Facebook business page (also known as a Facebook fan page) can be a great way to promote your real estate business, even taking the place of a standard website if you don't have one yet. (Facebook business pages are free, versatile and easy for non-techies to edit and add content to.)
The problem is that 90% of agents who want to gear up on the social media scale end up never getting around to it. If that sounds like you, I recommend checking out Mike Mueller's AreWeConnected site and possibly hiring him to set up your Facebook business page for you. I haven' t used this service myself, but I'm a fan of his own Facebook business page and I can tell he's really active on there and on Active Rain; overall, he seems to really know his stuff.
Here's the link: http://areweconnected.com/facebook/ - if you scroll down the page you'll see samples of Facebook business fan pages he has created.
