いつかこれがビジネスになればなあと


Would be grateful if someone could translate the following:

> いつかこれがビジネスになれば **なあ** と

I'm also not sure what the function of "な" is in the end part になればなあと.

My translation attempt: Someday this will become a business after.




This なあ (also written as なぁ, なー, な) is a sentence-final particle with several
meanings, but here it is used to add deep emotion. It's like "oh" or an
exclamation mark in English.

  * おいしいなあ。 Oh it's delicious.
  * 上手だなあ。 You're so skillful!
  * よく食べるなあ。 Oh you're a big eater!

This type of なあ can follow a ば-form, too, like so:

  * もっとお金があれば…。 If I had more money...
  * もっとお金があればなあ。 Oh if only I had more money!

Likewise, いつかこれがビジネスになればなあ means "I wish this will become a business some
day". The speaker is feeling the chance is not very high. と at the end is just
a quotative particle that indicates this is what someone said or thought.
