Optimizing the Speaker-Planner Partnership

As a speakers bureau, we hear from numerous speakers throughout the year who are seeking representation and ultimately, bookings! Last Friday, I personally received calls from three speakers. Some of the speakers I hear from are speakers who are just trying to get into "the business," but many of the speakers who call or email have proven track records. They are great speakers. So, we have great speakers looking for events, and there are thousands of planners looking for great speakers. That inspired this question: how can speakers and planners better find one another? I know for a fact that most planners receive more unsolicited calls and emails from speakers than they desire, so that's not the best practice. So what is? Planners, how would you like to find out about speakers? Does your current system work well? If so, what is that system? Is there a better way that would make your life easier? For all the bureaus and speakers out there, how can we better serve you?
