Do some 3D Modelling in Revit

We are a Melbourne based Design and Construct business and will be showcasing at an engineering expo in March 2017. We require a revit modeller to produce a 3d model of a Factory including a cross section of the Factory internals showing the walls, pipes, electric (advantage if you are familiar with MEP). We just need the visual, no detailing. We will provide adequate autocad 2D files and generic 3D files where available. The design will ultimately be printed on a 6m x 3m banner.
