Here is how to create your Facebook custom URL for you business page. You must be an administrator of the Facebook Page and logged into Facebook.
Visit the page http://www.facebook.com/username where you will be able to choose your username. Choose wisely as you will not be able to edit or transfer this username once it is set.
