How Do I Get Permission To Use Copyright Music In A Commercial For A School Project That May Be Aired Locally?

For a school project I have to put together a 60 sec commercial for a local business that may be played on local TV. (I will not be paid) I want to use the song “Do You Believe in Magic” sung by Ally & A.J. or The Lovin’ Spoonfuls. How do I get permission to use their music in my commercial?
