The problem with the ATR rating is that there aren't so many operators in Europe, and amongst them there are 2 BIG rubbish companies which are Swiftair and Farnair who offer
pay and
working conditions, they hire guys whithout rating and after 500 hours on type they are fired, that means you are overqualified for them if you already have the type rating, and, there are more and more guys with 500 hours on type looking for a job on the ATR.
The best idea for you is to apply to ALL ATR operators in the world, and you'll see what you get. If you're lucky enough to choose, that'll be great.
As for Air Contractors, we were expecting a big expansion plan for 2012 with the ATR fleet, but the latest news are pretty bad. So don't expect any recrutment from them for the time being.
