if you’re in charge of such events for anyone you may want to consider a magician to entertain the crowd. we spend so much time on our computers and it can take a toll on our bodies. if the project owner seems to think that it’s worth enough to find the materials by themselves, there should be a clear agreement about the responsibility areas of each party before signing the contract. please get in touch if you have any specific requirements. i don’t like having my photo taken.
