Generally speaking, with the exception of celebrity speakers, fees are a reflection of the guarantee. A low fee speaker might do well on a good day. But if you have to hope that your speaker is having a good day, you might do well to invest more to get more assurance.
Brad charges for value. This means that he doesn’t charge by the hour or the minute. He doesn’t charge more depending on the audience. He sets his fee depending on what value you need. Theoretically you have hired a motivational speaker because you need your people thinking or acting differently. What is that worth to you? And what would it mean to you and your organization if your speaker could deliver?
The truth is that pricing is ridiculously difficult without knowing more about your event, what you need, what your people need to hear, how much planning and customization you and Brad feel is important to guarantee success, and six or eight different additional variables.
