Who can move prebuilt office from Rosslyn to Johannesburg?

[Justloadit]

I have a project which was assembled into a one bedroom plastic prefab house in Rosslyn, which now must be moved to my offices in Johannesburg.

They need to strip it down, which includes plumbing, electrical and mechanical, and erect it at my premises.

Does anyone know of a machine move/rigger who would do this in the Johannesburg area?
