Does anyone know of a place in Louisville, Ky to rent a car that rents to people under 21?

I'm going with a group of friends to Gulf Shores in July and one of the cars we were gonna use to get there fell through. So now we are in desperate need of another car. I've been told that most places you have to be 25, but I'm hoping that there is one who will rent to 19 year olds.
