Unless you're still trying to get your 25 likes for the shorter URL,.. what is the point of having other shiners "like" your business page? To be honest it could backfire if someone local "likes" your page as you're pretty much giving them a quick link to your most internet aware customers!!!
I find my facebook page doesn't bring in much work,.. but when combined with my websites etc it is worth the hassle just about. I've added facebook widgets to my websites & "Find us on Facebook" logo's to my windows cleaned tickets etc, and my fan count is slowly but steadily rising.
