Most DJs charge a grip of money and do not offer discounts for smaller events. They have a good reason to. Most people need a DJ on Saturday, sometimes on Friday and Sunday but rarely any other day of the week. Since the options of when a DJ may be hired are limited to a small number of days a DJ will have a set price regardless of how small your event is. This will most likely not be the best option for you if you’re on a budget. Instead look for a part-time or hobbyist DJ that does not heavily relay on the money he or she makes from DJ’ing. Part-time or hobbyist DJs will be your best bet as they mostly DJ for the pure enjoyment of it. Since they have a primary source of income, anything they make on the side as a DJ is pure gravy.
