User Self Service Site customization?

I have a client that would like to add a footer message on the User Self Service Site, when a useris initially searching for their account.  A simple "For help call xxx-xxx-xxxx" message.

I'm unable to determine where I can add this message looking through the files myself, has anyone had a similar request or can point me in the right direction to add this message?

 

Thank you,

-Kyle
