Cityjet recruit through Sigmar recruitment [broken link removed] (Choose "Sigmar Aviation" drop down on theior website), I looked at this as I had the same dream, but the cost was crazy (around €100k). They had aa crowd advising on loans etc, and it might be easier to secure if there was some sort of guarantee of employmenyt ay the end of it. Still risky though.
An alternative would be to secure your PPL then CPL (single engine rating), the cost would be much lower, even in Ireland you could do this I reckon for around €10 - €15k. You might be lucky and get in with Aer Arran, smaller airlines or even Aer Lingus armed with a decent PPL / CPL rating. Some people people did it this way and have been lucky to get onto a training programme. Have you looked into this?
