Alcohol sales can be an excellent way to make some revenue at your event. If you plan to sell alcohol however, a liquor license must be obtained from your local governing body. Start the application process well in advance of your event as the approval can take up to 3 months in certain areas.

You'll be required to provide adequately segregated areas for the sale and consumption of alcohol if it is an all ages show. This will need to be clearly marked on you site map. Meet with your security team and go over how you are going to handle I.D'ing patrons as well as dealing with intoxicated individuals. I have attached a "House Rules" document that can be used or adjusted to suit your event.

Bar staff will also need to be hired. It is unlikely you will want to use volunteers as bar staff need to be certified to serve alcohol in most places. You may want to consider using a professional service as they are trained to handle crowds as well as the fact they will also be dealing with your cash!
