The old adage that good help is hard to find is more relevant now than ever before, says a spokesman for the Guild of Professional Butlers.

Charles MacPherson says butlers are in high demand thanks to a bustling economy that's created a new group of millionaires and billionaires.

"If we doubled the number of butlers, they wouldn't be without work," Charles MacPherson told the Daily Mail. "The new billionaires now want to live like billionaires and the demand has overwhelmed us."

Butlers today are called upon to perform a variety of tasks, from managing a household to arranging travel and planning dinner parties.

Robert Watson, president of the guild of professional English Butlers, says the job's demand for discretion and privacy has caused a decline in the recruitment.

"A lot of people do not know about this world, it's a very closed world," he told the Australian Broadcasting Corporation.

"If you're Mr. Megabucks and you want a butler you don't just go out and advertise and so a lot of people don't see it as a profession anymore, people that we come across they sort of drift into it and then suddenly their eyes are open and they think 'wow!"
