Office Move

I am the IT Specialist in an office of 65 Users. Basically if it plugs into a wall, I am in charge of it. I have been asked to come up a preliminary checklist and a list of issues that we may run into during the move in June of 2003. Does anyone have a basic checklist that can get me started, or if you have moved an office of this size, can you let me know what pitfalls I may run into. Thank you.
