It's much easier to operate a fb business page if you have a personal page too. I've changed my personal one to my business name too
So, it's the best of both worlds......people can like your page plus add you as a friend. The more people that add you as a friend, the more people get to see your 'business name' on their friends list
Fb is a fabulous marketing tool if you stick with it. So far, we've got 80% of our customers through it. Ask satisfied customers if they wouldn't mind leaving feedback (it does wonders for getting new customers), and post pics of recent work.
