As a profession? The easiest way would be to invest lots of time and money learning to play the flute, join an organization that can afford to buy one, volunteer be an understudy to someone else who is currently playing one and hope they retire. ...or buy one yourself if you can. They're expensive - very expensive!How in the hell does one get into playing something like that?
On the other hand, the companies bring their instruments to the National Flute Association's annual convention, which gives the attendees a chance to play around with the expensive toys.
