"any sources that may be available for purchasing some animation"
Sorry for the late response – I have been away for a few days. No, I don't
have any sources for purchasing animations. I'm surprised I don't see anyone
having stepped in with a response though, since there are quite a few animators
here.
Are you looking for custom animations – an animator to do some work for you?
Or something like animated clip art? We have had some animation clip art
available in the past, which later was released on a CD that was included with
Multimedia Explorer (no longer for sale). Perhaps you could find old stock.
