How to become a bike mechanic?

part-time - im in college at the mo. - summer hollidays soon, but im going on a few holidays then, so irregular time, rather than part time :-P

i've cycled all my life, and so have basic experience; off the top of my head, i can:
i can fix a punture
get a chain on/off
adjust saddles/handlebars
mess with add-ons (lights, bells, water bottle holders etc.)
set a bike up if its delivered in a almost ready to ride format (handlebars, wheels, pedals, rack, etc.)

no offense, but if u wanna become a bike mechanics, u should have a list of what u cannot do, rather than what u can do
