I'm creating a sample library for halion and need a few vocal samples, simple ooh's and aahs with real vibrato. If anyone can help me out, that would be great. You must be okay with a commercial use though. It will be a small libary. At most, I expect to make 700 hundreds dollars of it. A few patches will use the vocal samples.
I could also use some sustained cello and other stringed instruments as well.
I know it is not much, but I guess we all need to start from somewhere, don't we? All the mentioned samples are either under CC license, or Royalty-free, similar to CC.
For more research I'd suggest you registering at KVR Audio and looking here.
