Hi,
is there any interest in self-recorded soundmaterial (mostly voice)?
I would do this for free.
As a native German speaker, I was amused when I was listening to the Goblins singing in German. 
I could record voicelines (maybe not singing…) in German or English (don’t know how my accent sounds like for you).
Maybe I can persuade my wife too.
I would use a Rode NT2-A and Roland Quad Capture to record (in semianechoic room if you wish so).
Beside that I am making music for almost 30 years, but never composed on paper (only in my head 
), but I could try to give it a shot if you give me a theme… But I am not sure about that.
