All I can suggest is that you check the Rick Steves book that covers Vienna. He usually mentions several local guides that he uses on his tours, so I would assume they are very reliable and if you tell them you were sent by Rick they won't want to mess up their relationship with him.
Will buy the appropriate Rick Steves books. I like to carry them and tear out pages to make them lighter as we go around and I do not like carrying my kindle and constantly trying to find the right page. Thanks.
