If you've send 29k to your friend I believe Blizzard will probably ban your account and your friends account. The whole reason Blizzard added a 1hour delay to the likes of sending mail / recieving auction house money is so they can track gold sellers and stop them.
Seeing you've send 29k will defenitely trigger an investigation, though not knowing the shape and form of the account it may not be a reason to ban them yet (depending on multiple sendments / good behaviour / how long the account is active and other sorts of possible values).
But it's quite possibly you will be flagged as a possible gold seller and your friend as the buyer, in both cases these are bannable offenses.
I'd pray nothing will happen, GL.
