If I had a nickel for every "consultants by the pound" pitch where they sent in just barely competent coders for me to review, I'd be a millionaire (all of the big subcontinent body shops are guilty of this). Then they've got the balls to pay these poor saps peanuts and attempt to bill me $100-200/hour (depending on how many hours they've spent in front of an Idiot's Guide to C## training video). Then you see all the even poorer saps who are going through 2 or 3 layers of additional consultancies before they make it to our HR dept's door. I feel bad for them, but...I'd rather just recruit at local universities and get people who have identifiable skills, already speak English that most folks can parse, and won't get rotated back to the subcontinent randomly as one or more of their handlers has "visa issues."
Talk to your local university with a decent Engineering or Comp Sci curriculum and start recruiting. Save time, money, aggravation, and help our own college grads get into the game. I refuse to even take calls from the body shops anymore even though my corporate overlords are trying to force the issue. It's just not worth the hassle.
