You are asking for them to spend a considerabe amount of their time on you. If you wrote me a super short mesage about my field (not medicine), I might feel too that this will be 30-60 minutes of my time wasted on a likely sales call.

On the other hand, if you write me a longer message, explaining your background and position, give me all the background info, and let me answer via email, I might be more inclined to help, assuming you demonstrate that you at least have some understanding of the field.

Alternatively, you could offer to pay people for their time, which is not something sales people typically do.
