Hi,
From my point Academia de Evora is probably the best school in Portugal.
You have other schools, for example in Tires, like Gestair you will probably spend € 60.000 or even more take in account a place to stay, food, etc....
In Portugal the schools that I know are in Porto called Nortavia, in Lisbon you have Gestair, Omni, Leavia and in Evora you have Academia de Evora probably the best and with better reputation from my point of view but the more expensive.
This is all my opion. If I where you before I choose any school I would visit them first and talk with the staff and see the facilities and all that.
Good luck.
