The former head of business studies at Pontypridd college, south Wales, is advertising his services on a website. Mr Whittock became the talk of the nation when he was caught helping Major Charles Ingram cheat his way to the pound;1 million prize on the ITV show by coughing to indicate the correct answers.
He was found guilty at Southwark Crown Court and given a 12-month suspended prison sentence and a pound;10,000 fine.
The new website - www.tecwenwhittock.com - which features a photograph of Mr Whittock smiling, is entitled "The Official Website of 'The Cougher'".
The website's home page says: "Tecwen is open to all offers of work and is currently writing a book about his experiences." It features "humorous quotes" about the case, including two from game-show host Chris Tarrant. It adds: "Tecwen is available for any occasions which require a speaker in the UK or abroad."
As the marketing section of the site points out: "Tecwen Whittock is a unique name and is instantly associated with coughing."
