Aki - like the sentence "a key", but shorten the ey part, like you`ve been interrupted midsentence.
Hope I make some sense!
Eero - like aero (-plane). Well, almost. I know I don`t make any sense. Italian is very close to how you should pronounce the names.
So... why you wanna move to Finland? Where do you live now? I`m Finnish, though I was born and raised in Sweden, so I don`t quite see the lure with Finland. Even if I will defend my country against nay sayers.
Good luck with the names!
