Whistling sound when accelerating

[CityTypeZ]

Help. whenever i accelerate there is a whistling sound from the engine bay. I went to PML they told me either the alternator or the belt bearing problem.
I do not have time to do a thorough check that day. anyway my car is out of warranty. alreay 3.5 years old.
Please advise if it is expensive to change the above mentioned part in PML? is other workshop able to do it at cheaper price?
