I would be very careful in creating two profiles. Facebook is very strict on this, here is a link to their terms
http://www.new.facebook.com/terms.php Your account must be in your own real name. Not your business name, a fake name, pen name, etc. Nor can you have duplicate accounts.
If they do find out they can close all your accounts, that means both profiles and any fan pages. So all of your work and networking will be lost.
I don't want to see anyone's account get deleted with all the work everyone puts in on them. I have heard a lot of accounts being closed down recently. Many because they are promoting their business too much on their personal profile.
I hope that helps
