Need 3D models and CAD drawings for dust collector designs

We have a 'sales drawing' which defines the general sizing for our standard series of dust collectors. What I need is a complete 3D assembly (step/iges) for each configuration, as well as a complete set of detail fabrication drawings for each configuration. I have a set of fabrication drawings to use as an example from a recent project, which demonstrate the level of detail needed for each standard configuration.
