"The number of people" or "a number of people? [closed]

I think you are trying to say "I am personally speaking to a number of people who are close to owners" (not the)

I wouldn't bother with saying "personally", because you are already saying "I", which means the same thing. So I would just say "I am speaking to a number of people who are close to owners" People like using personally for emphasis, so it is not incorrect.
