Addition of Login Header Message Area

Can anyone help us figure out how to add this message to the top of our wp-login.php page?

Currently when a visitor clicks on the purchase of a member providers Book Me Service button it redirects them to this login page but we need to explain they must login to book the users service and at this time it is blank and just asks for login user name and password…

e.g. we need to show just below the header TALENT AND CLIENT LOGIN area and above the login fields this explanation text…
“Opps Sorry! You Must Login OR Register to Audition FREE or Hire this Voice Talent. If You Are a Member Login Below or Register FREE as a Client Using the Register Button Below! You Can Then Audition or Book Any Voice Talent. ”

We can not figure out how to add this to this page https://www.unitedvoicetalent.com/wp-login.php

Please see attached image of the page as it appears now… Thank you! :–)
