The vast majority of integrated courses will require you to pay anywhere from €60k-€110k, with a few costing even more. There are a small number of places on courses which are funded by airlines, or where the airline acts as a loan guarantor, such places are very few and far between in this day and age. The best bet is simply to keep an eye on here and on the flight training press for any announcements of such programmes.
The alternative is to get a job and fund training yourself, the modular route as mentioned by other posters is cheaper (it can be done for approximately €50k-€70k) and will enable yourself to train, to an extent, around a job. There are quite a few people who've saved through their late teens and early twenties and commence flying in their late twenties or early thirties.
