Hi Angela,
It sounds like you trying to construct an RFP for labor so I would pose the question to the Sourcing User Group to see if anyone has developed a contingent labor template or can share any practices on sourcing for labor and specifically on how to make the best use of the content creation and scoring capabilities for your purpose.
However you may also want to also consider looking at the capabilities of Ariba Services Procurement which is specifically designed for evaluation of temporary labor. In fact, one of the requested features is to add a side-by-side comparison of candidates which is a feature currently under evaluation by our Product Management group.
More information on Services Procurement can be found below:
Let me know if you need more information.
Thanks,
Tommy
