Hi Leee
Working in the UK; Thomas's reply seems to have just about summed up the ball park figures people ask for over here, (Offshore captain 2500hrs). The north sea has no apparent fixed lower limit for co pilots, especially if they just need bums on seats. The rest are a good guide, though I will say that if you ended up in the right place at the right time it almost doesn't matter how many hours you have, provided you have the right pieces of paper.
They are however probably the most expensive peices of paper you will ever purchace. Don't want to discourage you but...CAA doesn't stand for the Committee Against Aviation for nothing.
To that end, can you or anyone else point me in the right direction to do some fire fighting, (obviously given the season South would be a good way to go). How would I go about getting validations and visa's etc to work the season in Australia for instance. There isn't a whole lot going on in the UK just now and I'm very keen to spread my rotors, so to speak.
Good luck all and fly safe.
