Do I need a contract?

Why do I need a contract? If I say I will DJ a gig I will DJ a gig. Well that's great and I hope that is true. But for the peace of mind for your customer, creating a contract is the best way to go. A contract will not only protect the customer, but it can also protect you as a DJ. For example, you are DJing a wedding reception and certain members of the crowd get a little too crazy and are threatening you or your equipment. Withing the contract there can be language that will allow you at your discretion to pack up your equipment and leave the gig. While this is an extreme example, I'm sure it does happen. It is better that you are protected than to have your equipment damaged.
So where do I get a contract. I'm sure you can go online and search for a contract, but this is far too important to leave to some random person. Search for a lawyer, discuss your needs for a contract and have it done professionally. Just like someone in need of a DJ, there is a person that can write a contract. Are you going to trust your neighbor to write it for you. Well, only if that person is a lawyer.
So, protect your customers. Give them confidence that you are a serious DJ and will act professionally. But not only that, protect yourself. You will be happy you did.
