Research and provide Videos from Youtube or any other source

I need two or three videos (short or medium) that I can show in a class room to attendees for a training course on Sales

I need the videos to be about Sales or Telesales or sales meeting

I dont want a video that is about retail consumer shop sales, I need a corporate sales the one that sales men visit clients and explain about the products and services

Preferably I want a video related to Insurance and Health care but its not a must any industry is accepted

The video can be even a clip from a movie that can be related and used for training

or a dedicated clip related to sales
