Several poker players have made a side living from coaching others down the years.
Perhaps the most famous of these is Men Nguyen, who has trained several members of his family into world class competitors, including David Pham and Minh Nguyen.
And now Roy Winston and Michael Binger are looking to enter the market.
Winston unveiled a new venture from the two of them in his Card Player blog and hopes to generate their first business at this year's World Series of Poker.
He claimed to have benefited from several years of tutoring himself and his firm "will concentrate on improving an individual poker player's performance through education and specific training".
Those willing to learn from Winston and Binger will receive advice from two of the world's best players, with a wealth of experience between them.
Both earned well over a $1 million in live tournaments over the years, with Winston earning more than that in one go when he took down the 2007 World Poker Tour Borgata Poker Open.
