How are you different from other Disc Jockey Entertainers?
As your DJ Entertainer, I never make myself the center of attention. I encourage your guests to have a good time, but it is done so in a low-key manner that won't detract from the fact that this is your party.
I provide contracts that protect your interests. Many of my competitors either do not provide contracts, or provide one-sided contracts. Also, I have a satisfaction guarantee. While others may claim to have one, mine is written right into my contract.
In addition to playing great music, I can incorporate mini-events and games into the party to make it even more entertaining. It will be a good time for everyone involved, whether they actively participate, or just watch.
I only play "Family-Friendly" music. I look at it this way. If I'd feel funny playing a song with my own mother present, then it's not something I want to play when your mother is present. The exception is when the guest of honor makes the request.
