Gary Schwartz: the voice of TF2's Heavy and DemoMan, SW:TOR's Guss Tuno, and DOTA2's Pugna, Shadow Shaman, Lich, and Sniper
Basically, by donating $50 or more to
this KickStarter and selecting the appropriate tier, he will record a short paragraph in the voice of your choice and send an mp3 to you (expected delivery is listed as February).
While he has definitely said it can't endorse any business or be used in anything you sell, I am currently trying to find if it's OK to use it in a publicly available plugin... using TF2's Prop Hunt Redux as an example.
