I've worked in law enforcement for 8 years and the hiring/promotion process is kind of interesting. In a way my agency used "contract interviewers."
The normal process includes some sort of written test to make sure the candidate meets some general baseline of intelligence. After that there is an oral board interview. It is usually a set list of questions on which the candidate's score is graded by 3 - 5 interviewers. For my agency the board usually consisted of the supervisor over the position applied for, someone doing the position applied for, a command staff member and 1 - 3 of the board were from a different agency.
I always thought it was odd that we used outside interviewers during our process. I believe the goal was to get an unbiased view of the candidates.
So, I could see a contract interviewer as a useful tool. Especially if the goal was to bring in someone who was unbiased. The obvious difficulty you would have to overcome would be the lack of knowledge concerning the specific business - what is their culture? How well would a candidate fit in?
