I'm willing to help you
I'll apply for voice-actin' for ya. Zeel1 refered me, so you know. I'm willing to do any voice you need, but I'm most experienced in doing Sonic and Shadow for now. E-mail me at sonic232 [at] gmail dot com, and I'll send you a link to a flash I'm working on right now that has samples of both of those voices. Decent flash, by the way, but you're definitelly going in the right direction by getting voice-actors.
