This is probably the most frequently asked question and unfortunately its not as easy as x or y. The cost depends on many factors, the DJ’s experience, up to 3 years for example, 3-5 years, 5-10 years and above 10 years. More experienced DJs will have been exposed to more scenarios and will usually be capable of getting any audience dancing and creating an atmosphere but their cost is higher.
The date, location, times for set up and performance are also factors. If set up is before dinner for example and sound is required for speeches etc then the day is much longer. What are the full sound and lighting requirements or will they be provided will also need to be answered and the get in, is there stairs or a long get in that will take hours to bring equipment in and out.
