An outside person has no "skin in the game," thereby creating a skewed incentive structure. Paid by the hour, the incentive is to process as few resumes as possible. Paid by the resume, the incentive is to reduce th effor per resume.

Personally, I this kind of work terribly tedious, at best. One would have to pay me at least double my normal rate.

The traditional model might call this role an "in house" conteract recruiter, and I doubt the good ones get paid what a good programmer or sysadmin do, thoug perhaps they should.
