I suspect it is a new course in field service work, when I got started I purchased an ebook about the subject (the only thing of value I got from the book was directed to www.sofi-usa.com, and I consider that alone worth the price of the book I bought, I think it was somewhere around 30 dollar. Sofi offers much better information, contacts and advice. Yes they do have material they sell, and it's well worth the price, but the most valuable thing they have is a yahoo group which is used for advertising field rep work, and it's free.
I too am interested in this I actually see the advertisement on quit a few sites. I have spoken to someone at the company I called and she answered I had a few questions that she answered. I am thinking of purchasing the book if there is a refund involved I will try it, at least if it is not true to the word I can get my money back.
