Where to start

Hi, I’m 16 years old in the uk and will be leaving school next year, (currently in year 11) and I want to be an artist manager or work in the music business industry helping artists. I would love to do an apprenticeship but I’m not sure where to look or if anyone will take 16 year olds. I’m able to travel to London and am based in the south east. Does anyone have any advice?
