I used to be very shy. Not any more. I still don't like crowds, and I prefer to be with one or two people - but I can make a speech for five or five hundred persons, who usually tell afterwards that it was the best part of their day - or the whole week. What helped: I went to a course in our university, "confidence as presenter" (bad translation of the name, sorry). The teacher was excellent, and I guess that is what really is what counts. So, my advice would be: go to some course about communications or such, but make sure that the teacher is excellent.
