Speaking as a chief pilot, I would never hire someone who offered their services for free. It smacks of low self esteem and is not what I want in the cockpit.
On a more positive note, if you have the inner urge to get your CPL, etc. then follow it. Destiny only works if you do your bit and you won't get a job without a licence. Use the trains to get what you need then start looking around - I wouldn't worry about jobs at your stage of the game.
