I have been working with a recruitment consultant (by this term I mean a person / firm which focuses on referring a candidate for an opening within a company). Until now, this had been for full-time roles, so if a candidate is placed successfully, the consultant takes 8.33% (1/12) of the yearly salary of the candidate.
For a certain project, I need to work with a freelancer, who would get paid per hour, or on a per-project basis. What would be the appropriate way of paying the recruitment consultant?
