He later opened Kush Fine Art galleries in Las Vegas and Laguna Beach, California. Many of his original oil paintings are also sold as giclée prints which initially contributed to his popularity. In 2007 Kush sued the pop singer Pink and her record company for copyright infringement when imagery from his painting (and later giclée print), Contes Erotiques, was used without his authorisation for her 2006 video U + Ur Hand. The case was settled the following year when the singer agreed to pay him undisclosed damages. Prints and an original oil painting by Kush are held in the NaPua Gallery collection at the Grand Wailea Resort on Maui in addition to works held in private collections. In July 2011 his works were shown at the Artistes du Monde international exhibition in Cannes where he won the American First Prize in Painting. He also has a resident show in Las Vegas, Nevada, at Caesar's Palace. In 2019, Kush filed a lawsuit against pop singer Ariana Grande for copyright infringement when his paintings The Candle and The Candle 2 was used without permission in her music video God is a woman. The lawsuit is now settled.
