The originating buyer wants quality work, probably as a one-off, but doesn't know or want to know how to find someone like that. Everyone is high risk.
A matchmaker company in the middle has ongoing relationships with the end contractor, knows their work is decent, and provides a framework / legal liability / insurance on top. The contractors they know are lower risk.
So the matchmaker can charge {full cost of high risk - slight discount} while knowing they're actually only taking on {lower risk}.
Where it seems to go pear-shaped is when the matchmaker gets too large and can no longer individually vouch for their contractors (e.g. IBM Services and globally integrated service companies).
