In reply to Mutley:
From my limited understanding of it yo either need to be climbing at an exceptionally high standard (maybe E7+ like the guy above said) or be in a very prominent position which will get you and as such they gear your using into the publics view (e.g. well known, respected professional guide or something like that).
There may be other ways of doing it but those are the main ways i know about. Its a sad fact the very few climbers will ever get sponsorship from any one. After all if gear companies went around sponsoring loads of people they'd have no one left to sell their kit too!
You'll probably just have to do what the rest of us do and save save save! Although you never know, you may get lucky,
Best of luck to you.
