Hi Sree,
What you said is very right but the overall programmed cost can be avoided in a SLA, cause many firms still have a variation in the cost based on recruitment procedure and position.
But the rest seems to be just right. It also would deal with the role definition of the employees invovled in the project and as well pre-interview, pre advertising, advertising, analysis & shortlisting, prepration of interview, interview, Record Checks and induction. In fact the entire process is detailed in the most possible way.
Regards,
AJ
