I'm looking for an app that will allow me to record multiple outgoing voice mail messages. I learned that it's possible with Google voice. Does any one know of such a thing?

Since your outgoing voicemail message is stored on your carrier's server, that would need to be some app.

Yes, I use Google Voice as my voicemail for my phone, rather than voicemail through my carrier. I have different voicemail messages for different groups and, a couple of personalized messages. For example, everyone from work gets one message, friends get another and my brother gets one just for him (drives him nuts!).
