this site: http://www.pixelprospector.com/indie-resources/ has voice actors.
For what they post voice actors?
Can i hire the voice actors from this site you gave? or in simple words, i want to make a game witch the voice actor of the main character is me and a girl character by Christina Vee for example, this is possible to do it? or i need my own voice actors?
Well, for sfx at least, try freesound.org. I'm a sample based musician, and this place is my playground. Tons of high quality WAV/Flac sounds, many recorded by sound pros in their off hours. I can't even begin to count all the awesome sounds I've found on there. Largely free to use for commercial products, though almost all request 'attribution'; ie give credit to where you got the sounds (seems more than fair to me). They even have a forum where you can request stuff and such.
