Hey Caz,
That job sure does sound like fun but ya gotta be smart and look beyond the obvious. You should interview people who do this sort of work and see what THEY REALLY HAVE TO SAY ABOUT THEIR JOBS -BEHIND THE SCENES. Things aren't always what they're cracked up to be. You can never have too much information. Granted, Mika would probably be a fabulous employer, but it's all very new and there are also many other players in this endeavor. So let's suppose the project appears above-board, you can always opt to do this part time just to get your feet wet and see how you really like it. No pressure, just make sure you have options and are free to make knowledgable and well-informed choices.
But I gotta say, Caz, knowing what I do know about you from this forum - your videos, competitions, bubbly personality, lovely fun extrovert - you are a shoe-in for this type of work - or any position that requires creativity, mingling with people, making them feel welcome, happy, very much at home and have loads of fun, to boot.
