Okay, I know itsu can be used for 'when' question ex.. when are we going to eat? 「いつ食べますか？」but what about for thing like.. When you finish this I'll be happy, or Ill pay you when you finish, or when you can do this then your ready..

If so then is there any special way in which it should be used that way. and if not what would be used?
