So how does one use Facebook to promote a small craft/niche business?

[eg]

I know people market their craft and small niche businesses on FB.For the life of me I can't figure out how to set something up to do this. I don't want to do it from my FB page that I use for friend and family posts. So how can I do this and keep them separate.
OK, a business entity page sound interesting; but so far I don't seem to find FB very user friendly when it come to exsplaning how to find things ( such as this) or even how to set it up.
I hope you will elaborate some on this. Thanks.
When I look at the sign up link I'm not sure which is the better option for me. Business or branding, both sound like they could fit but; neither gives an explanation as to their function or purpose on what they specifically are or do.

Make a business Page http://www.facebook.com/pages you can create a page thats separate

Okay, so you've got two options. Set up a business entity page (like your personal page except that you can only "like it" as opposed to friending it) or you can actually advertise on FB. The former is free, and the later is not.
