Video presentation script

I need to make a 5 minutes video presented for this subject. I do not have to time to any things about it so I want a full script for 5 minutes so I can just record the video. There are 5 topics and one minute on each topic is required. Do research for each topic and provide references in Harvard Style. Atleast 5 references are required, one for each at least.

You are required to describe what the key responsibilities for a professional communicator are, including types of audiences, key messages and delivery modes if you worked for:

1. a major public hospital
2. a large retail department store
3. a large international bank
4. a large government state high school
5. a large music store.

It is important that you describe these responsibilities for each of the five types, so you might spend a minute on each.

See the attached file for further details.
