either real or imagined:
1) Disparaging remarks about the training I have just received and the trainers that provided it will not convince me that I need to train with you.
2) If I ask you what you teach, I expect an answer. A question is not an answer. Asking me what I want to know is a question, the answer being "I want to know what you teach" which, oddly enough, was the original question.
3) If you can offer "the same class" at 1/3 the price I will probably expect 1/3 the training, either in facilities or in experience. In your case I would assume both.
