Jim go for it mate, I went for a Group pensions manager job in town when I was 19. Had 6 months experience and got the job.
Maybe because I was only looking for a salary of 5k less than what I should have been earning

but fool me I didn't know that. £1200 a month after tax was a lot of money for a 19 yearold!
Go for it mate, what you got to lose.
