Anyone is interested in being a voice actor for free, maybe for experience?

I'm making an animated series, genre: Action, Drama, Romance, Comedy, Thrill.
I wish to have some voice actors who can speak japanese, it doesn't matter if you're foreigners but learning japanese, i will gladly take anyone. Even though the animation scenes are still being made, id like to take someone as soon as possible. Need to be in touch a long term. I will give the character specifications once dm'd. Your help is much appreciated.
