Sports agency Paul Ridley Ltd – run by the former Sun sports editor – will also promote charity and fundraising events, and a website.
Some traditionalists find the army's chanting disruptive, but Ridley will promote their good-natured spirit.
Barmy Army senior organiser Katy Cooke said: ‘We get requests for interviews, and phonecalls from universities and children, all the time. We need someone with press experience and contacts.'
The move comes as England prepare to face Pakistan in the second Test. The team heads to Australia for the Ashes this winter.
Ridley will also bid to get a branded comic strip in a national newspaper. It features the Barmy Army's ‘Jimmy', who is ubiquitous at English cricket matches and famous for looking like aged entertainer Jimmy Saville.
The army was formed as a merchandising business after Australian press mocked fans for travelling Down Under when the national team had little chance of winning matches on the 1994/95 tour.
