Fantasy Broker: A postal clerk wants to be a stand-up comedian for one night. A businessman wants to drive a freight train across a western State. A psychiatrist wants 20 dates on 20 weekends with 20 girls from 20 different countries. How do they do it? They see a fantasy broker whose business is making dreams come true. Originally pioneered in Chicago by an advertising executive, fantasy firms in several cities now do a booming business, charging from $150 to thousands to turn dreams into reality. Fantasy Fulfillment Institute in Washington, D.C., did $2,500 worth of business as a result of an ad that read.
