I'm about to begin planning an upgrade to ZCS7 for this fall, but before we make the switch I'm trying to find a trainer that can aid my users in transitioning to the new version.

Does anyone know of any group or individual who has a ZCS7 training program that I might be able to contract to run a 1-2 day onsite training?

While I'm aware that the differences are subtle between the versions from an end user perspective, the culture of our organization adapts best to these kind of changes when someone from the outside comes in to aid the transition.
