3dMax Maya Mental ray

I have a large warehouse scene which was purchased from turbosquid (3ds / maya with mental ray), we need our product put in place and rendered. Our product is a pallet, so all the pallets in the view would need to be replaced with out model. This is the rendered view and model purchased: https://www.turbosquid.com/3d-models/full-warehouse-with-forklifts-3d-1759951#

We designed our product in solidworks as an assembly, this can be provided as STEP, IGES, etc
