Another thing most companies don't have their own clients, they tell you they do so that you come and sign the contract. What they do after the training is post your resume in Dice.com, monster.com and send your resume to the wanted jobs posted in those and they send you resume to the vendors (other consulting companies so they do corp-corp contract with those vendors)
So after the training you can wait for them to place you or start sending out ur own resume.
And usually a placement can take from 1 week to over 3 months that really depends on what you know and how lucky you are.
