Try Monarch - recruiting for most types and bases. Don't be fooled into thinking Monarch is the airline it's reputation would have you believe though. It's now an hour building airline for those young enough to move on once they have a few thousand jet hours. Still good as a first or second job though.

PS Don't worry too much about the hours requirement on the website. Many people have gotten in with minimal experience.
