You could try the Swedish Consulate in LA. I'm sure they could point you in the right direction.

Otherwise see if you can find a language school that teaches Swedish or a College/University language department that offers Svensk.
If I was down there, I'd be happy to help you, but from where I am, this is the best I can do for you.
Just out of curiosity, which songs are you planning on doing?
Lykke til!
