What status are he coins in??
Are they Pending?? what?
He probably just managed to get the addresses in bc.i. Sweep wouldn't work there anyway. He still can't send transaction because blockchain.info is bad at handling fees and has no flexible settings.
There is a custom send option in which you can send with your desired fee. I tried it too, though it doesn't go through either. I haven't tried the email or sms method yet. Will check it out and see what comes out of it.
