You can be more specific in writing your requirements. You mention, all engineering departments. What do you mean by that ? Do you require engineering or technical trainers or soft skill trainers ? I do conduct soft skill training for engineering colleges, mba schools, arts & science colleges etc. So, I would suggest that please formulate your thoughts and requirements and post suitably so that you get the right kind of people to meet your requirements. Am a member in several trainer groups pan India. Hence, your clarity will help you a great deal.
