1-800-karaoke also provides professional mobile dj/kj services throughout southern california and through our affiliates we may have a dj/kj available near you. costs will vary depending on the size of your event. smaller venues will usually range between $450 to $550 for a three to four hour event. once you decide to use our services a deposit of half of the total will be required to reserve the event. the deposit is non-refundable. however if you need to cancel the event (the wedding is called off, family emergency, etc.) your deposit can be used for a different date provided we are given two weeks notice. call us at 1-800-karaoke for more information or to reserve your event now!
