Being a champion of world class service is always the goal and stories like this never get old. Keep in mind that there are also hidden/intangible costs associated with delivery of this level of service, for every "Bob the 4 million dollar client", there are 10 "John the 2 hour time-syncs". I am not saying that you should not strive for world-class service, because you should. I would speak more to pricing your services accordingly and not under valuing them to the point where you cannot take care of clients properly.
