I have a contract, which I use for weddings that I shoot. It is based on famous Hollywood Wedding Photographer Joe Buissink. I will send you a document with the contract. You are welcome to add/take out any bits accordingly. It is a very in-depth contract and has been used by Joe Buissink on loads of weddings and events that he has covered. For me, it covers everything.
If you have any questions, please feel free to ask.
