I have both. My Facebook page is only for business (not personal). I created my page as a business and do not list any personal info on the FB page.
Actually for this type of business you need to be on most social networks and all the IM's. This is the best way to stay in contact with a variety of clients and attract new clients. (I am not a big fan of social networking, but I created the accounts out of necessity for my VA business.) Since I have so many accounts I use
Digsby to monitor all my accounts.
