Rap my new Lyrics to Instrumental Song

I have a welcome speech I am making with another girl for an event we are having next tuesday.. its a lip sync battle. her and i are the chair and vice chair of the event and therefore couldn't perform. we decided to write our script to be very similar to the beat/lyrics/rhymes of warren g's regulate. we were hoping to find someone who could take the instrumental of that song, and rap the words of our script to it in the same way that he does that song... is this something you can do?? how much? how fast? we were hoping to have it asap so we can listen to it and memorize it, so we can lip sync it at the event tuesday.. :slightly_smiling_face:
