Received a phone call today from someone who wants to "refer lots of patients" to us and wants to know if it's okay that there is "a small service fee" at the end of the month.

When I specifically asked what company he worked for, he said IDEARC.  

My internet search showed that IDEARC is Verizon's yellow pages vendor.  Interesting way to NOT say you are selling an online yellow pages listing.

Does anyone know anything about this company?  Personally, I don't have any interest in doing business with someone who tries that hard to obscure their intention.
