Quinceanera

Hey i need help! What i want to do for my Quince Dance with my court is to have a mixture of songs. It will start out as a waltz, like most Quinces do, and then it is going to go into a bunch of old songs we all love and know. Like Le Freak from the 70s and songs from Grease! And then it will turn back into a waltz. The only problem is that i am having troubls finding someone to mix the music. What should i do? And do i create the dance on my own or do i find someone? No one if my family can dance anywhere near as well as me. (took classes since i was a baby) So what do i do?
