I've got a Facebook fan page, How do I get more people to join it?

Hi all,

I've created a fan page for a small family business my family and I run (we have a small music studio). As the relatively 'technical' person in the family (I know just enough html to color the background of page) I got the job of running our facebook fan page.

I started reading all those "10 tips for the best…" tutorials out there on the web, but from some reason I am pretty skeptic. I keep feeling people are trying to sell me their services.

What I'd like to hear is some good advice from people who perhaps succeeded themselves in building a good facebook fan page. Also, I would like to unfold the mystery behind the real figures. I understand that everyone these days must have a faceook fan page, but how much money \ how many customers can I really expect to gain from this?

Thank you,
