Dear Mr. Bhel,
My intention is not to hurt you or to degrade the institution you belong to. I primarily want to clarify it. If you had perceived the message in another way, then my apologies to you.
I'm just concerned about your inquiry for a free training session (or workshop as you term it now) for your school. Whether the session is for students or for faculty, there should be some value when someone is offering their expertise, spending time and effort for the betterment of your staff. The school management should also reciprocate with some value, honoring their expertise. How much you pay is not the criterion, but there should be some mutual exchange. Expecting free service does not sound good and looks odd. It is prudent to refer to the phrase "if the service is free, you're the product." Some beginners, to test their presentation/training skills, will use your school as a platform to enhance their public speaking skills. Ultimately, your expectations for the session will be defeated.
The quality of any service or product depends on how much we pay for it!
I hope you will perceive my thoughts in the right spirit.
