Your age isnīt a problem.. one of my friends is 45 and he was done with his ATPL theory about 5 months ago and he was hired just a week ago by a regional here in Sweden just after he was done with the Multi eng training, ok he has flown single engine alot but still he is training to become a Captain now =)
Iīm currently in the end of the ATPL stage. Doing my training at a school here in sweden that does train people from scratch to the requirements needed to be hired by an airline.. but still you just come out with about 210hrs so when you come out it is not very easy to look attractive to the airlines
But if you really want something and dont give up i bet you will sit in the left seat someday =)
My training costs me approx 70 000 euros. not cheap but i dont know the prices in other parts of the world
Good luck
