Buzz Agents

My company has decided to start a new "buzz-agent" campaign.  They are calling them the "all volunteer army".  My company makes medical devices and having our patients recommend our product to others is a great way to expand business.  Doctors are not allowed to recommend products from specific vendors due to liabilities.  What better way is there to promote a product then by a person that is already implanted with that product?  

It will be interesting to see how this new program affects our overall sales.
