loan
hello,
I don't know if it's possible in Ireland but i did my training with some money from my parants but the biggest part came from a loan from the bank with not to bad conditions which they made specific for pilots in training.
I don't know the specifics by heart but you only start paying back the loan when you start receiving salary.
My advice is go to some banks and gain information
(the same for the flight schools, in some you have greater chance to get a job)
