Why not all our speakers are on this website

We have a database of now well over two hundred speakers and if you count well, you will see that we list only thirty or so on this website. That has raised some misunderstandings both with our speakers (who thought they would get an automatic listing on this website) and with potential customers who also thought we would list all our speakers here.
Although we love the internet and use almost any tool to promote our service, we thought giving away all our goodies would not benefit our service in the long run. So, the website gives an overview of some of our speakers.
How do we make our pick? First, speakers have to go through a rather rigid internal screening procedure. A speaker might do a marvellous job on one assignment, but they might not match another one. Our work is to make the best possible match. Before we assign a speech to a speaker, mostly one of us has seen him or her in action and can give a reasonable assessment. When we have not seen a speaker, we rely on information from other third parties, but might still be reluctant to work with him or her.
When we start working with a speaker, we ask if they want to be listed here, and some of our celebrity speakers prefer not to. Others well-known speakers are out for more profane reasons, like we still do not have a good picture of them. Sometmes we are still working on profiles.
Further, we have a wide range of expert speakers, who would focus on a rather narrow interest: mobile marketing, security systems at the stock market, sourcing, city planning, HR-management, China's internet censorship, you name it and we come up with a solution. They would do very well when your meeting focuses by accident on those subjects, but we have decided in most cases to keep those experts in our database and not on our website.
There is much more to say about this, but since a few of you have asked, I though I should explain a bit about the background. Do let me know if you have more questions.
