We do have a number of members who are prepared to give talks to various groups. However their availability and the distance they are prepared to travel to give a talk are very much up to them.
If you give us some details (see below) we will contact our members to see if anyone is prepared to give the talk you are requesting and if they are, we will ask the member to contact you directly. We cannot of course guarantee that anyone will respond to your request.
Please include the location / dates and time of when you would like the talk with your request.
