Before you book a corporate standup comedian for an event, company or conference, start with figuring out what you want. When you call or email the comedian, ask what technical requirements they might have. If you’re dealing with a booking service it should be absolutely fine to ask them how they’re compensated and how much of the fee actually goes to the comedian. You might also ask them if they’ll have a representative on-site to meet with you and to deal with anything that might have to be fine-tuned before the presentation.
