Need Maragarita large batch help

[Kae]

Ok my friends & I need a recipe for about 6 gallons of Margaritas to put in a machine. my friend got a machine & we need to make a large batch for the weekend. I would like to use a Mix such as Dailys I thought Dailys site would have a batch recipe but it doesn't. Does anyone have a machine or rented one?

Thanks

Kae
