What was the amount of total domestic annual revenues generated by
contingency staffing companies (ie contingency recruiting companies)
in 2002 and 2003 as a product of GDP?  It may be easier to look for an
estimate of total expenditures by US firms for CONTINGENCY recruiting
fees.  I am also looking for a detail or break down of total
contingency recruiting revenues by industry or sector.  I NEED THE
ANSWER TO BE SPECIFIC TO CONTINGENCY RECRUITING IN THE US ONLY please
(as opposed to staffing services or retained search.)
