AutoCAD Design from Maya export.

Hi I am creating a model in Maya. It needs to be exported from Maya and imported into Autocad. The model will then need to be tweaked and cleaned up, and have accurate measurements done and annotations on its dimensions. The final file, must be prepared ready for the factories to make its mold. Please only bid, if you have Maya, and have had experience converting maya models into Autocad for measurements and annotation. The final exported files MUST be STEP (.stp), and AutoCAD (.dwg, 3D only) and STL The model in autoCAD must be in 3d when exported. Not 2D. I have attached and example. Cheers Nick
