Brian,
You might be able to work a catchy ad pitch on the promo piece you are developing. I'm thinking create a short film (ie: a 30 sec commercial) that sets a scenerio involving a "typical web client looking for work" and use your puppet actors to pitch the ideas like "So ya need flash programming, eh? We DO THAT!" "So ya need flash with puppets? We do THAT, too!" "So ya don't need any web stuff at all, but want to impress the heck outta your customers using puppets? (and c'mon, EVERYBODY loves puppets!) Well, you're in luck, Slappy! WE REALLY LOVE DOIN' THAT, TOO!"
Check out Jim Henson's pitch film he created to sell the idea of Sesame Street to PBS back in the day (it's on Sesame Street Old School DVD set vol 1). It uses the same notion that I am referring to here: use your stuff (ie: skills, puppets, etc) to turn potential client onto your stuff, which, in turn, makes them want to use your stuff to improve and market their stuff.
