They won't look closely. As you seem to see yourself, they would rather spend $50k per engineer to a 3rd party service than perform proper recruiting by themselves in house.
You seem to be trolling, but to clarify I was suggesting Starfighter would be looking closely before referring candidates to clients. Their reputation depends on the quality of the candidates they refer.
I'm not sure why you're being downvoted. Obviously, if they reference Danny the Word programmer as a ninja rockstar to a Fortune 500 on a regular basis, their business is going to take a nosedive.
