V-Ray materializing of 3DS Max 2015 scene. - open to bidding

I have a 3DS max scene that is arranged form an FBX import. I need this scene re-materialized using high quality V-Ray materials as found in Evermotion package or at [login to view URL] or similar. High quality is important. We do scene setup and rendering in-house, but we are looking for a new outsoursing partner for our team, so if we are satisfied with quality, then we have plenty of more work coming. Please concider that imported FBX will be updated and re-linked later, so it is important that you keep all existing materials in scene and modify these to V-Ray. We do this by changing existing material to an "Multi Sub material" and then adding "edit mesh modifier" to the objects. Then we add prefered new V-Ray materials to the differnt SubMaterial slots in this MultiSub Object setup. (You may need to modify mesh IDs using the Edit Mesh modifier to get correct new V-Ray material to appear on correct object. Afer complete re-materializing using this method, we then will be able to reimport the updated FBX file and ALSO keeping all new 3DS Max materials in scene. This method is used to be able to arrange 3DS Max render and material setup eaven before the model is finished in Revit by our architect. We use 3DS Max 2015 and V-Ray 2015.
