Metal frames on casters for plywood wall dividers - URGENT

I have purchased six 2.5m x 1.2m pieces of plywood and want to make them into some moveable wall dividers on caster wheels. I need them to have a metal frame so they stand up and are sturdy. They also need to be able to connect to each other so they cannot be pulled apart unless unclipped. This job is reasonably urgent. Need by the end of next week. Any help would be appreciated.
