Anything can sell if you know how to market it – that is what 26-year old Jason Sadler has proved. He sells T-shirts with the message of his advertiser printed on it and has earned $83,000 this year. He calls it the ‘human billboard service’. He markets the T-shirts through social networking sites. He wears the T-shirt, blogs on the topic, runs YouTube videos with him wearing it and uses the twitter – even if he sells one T-shirt every day with the logic of costing that he has developed, he can earn much more than an ordinary person. His rates are very clear – and innovative: the price depends on the day of the year – if it is the first of January, he charges $1 but if it is the 31st of December, he charges $365. Jason plans to introduce the service next year in the West Coast by hiring another human billboard.
