The publicist said that the Italian chef had been given a "huge shop window" to advertise himself on the ITV1 show.
"Gino could easily make a million in the first year and £5m the year after. The show is a huge shop window and just about everyone I've spoken to says he's the outstanding character on it," Clifford told The Mirror.
"He needs to have his own series, something like cooking celebrities' favourite recipes, which gives him the chance to be funny and cheeky. The sky's the limit."
Jonathan Shalit, who is the agent for former jungle celebrities Christopher Biggins and Myleene Klass, commented: "The TV chef market is crowded but people like cooking and I'm A Celebrity. If you've had 8.5 million people watching then you've got a headstart."
D'Acampo was named 2009's King of the Jungle after beating celebrity cleaner Kim Woodburn and snooker star Jimmy White in Friday night's final.
