Looking for Volunteer Voices

I am in the process of converting my book Future Imperfect into an audiobook. It has embedded quotes from a wide variety of sources and it occurred to me that, instead of reading all of them myself, I should get each read in a voice different from mine and more suitable to the person I am quoting. The voices I need are:Chinese accent (for "May you live in interesting times")English accent (Arthur Clarke, George Orwell, Samuel Johnson)New York accent, possibly Queens (Richard Feynman)Sophisticated East Coast accent (William F. Buckley)Russian accent (Manny from The Moon is a Harsh Mistress — other accents for him are possible — and a KGB agent from "The President's Analyst")Mark Twain accent (recordings probably exist)H.L.Mencken accent (a recording of an interview exists)Female Cornell administratorFemale scientist (a different female voice from the preceding) Girl's voice — Dorothy from The Wizard of OzSexy woman's voiceFrench accentArabic accentShakespearean actor (Hamlet)There are a number of other quotes that just need a clearly understandable voice that isn't mine.It may be a crazy idea, and I may give up and do all the quotes myself, but I thought that the magic of the internet and the open source approach to doing it might work.Most of the accents should be mild — I want all of the quotes to be easily understandable.
