Convert Drawings to Autocad Inventor

I have about 500 simple paper drawings that I'm scanning into PDF form. I need them converted into Autocad Inventor Format. We're currently using Inventor 2011, but any recent version of Inventor is fine. Please note: This auction is for 50 drawings. I will likely have multiple workers work on this project concurrently, and will have multiple projects until all drawings are converted into Inventor. Again, this auction is for 50 drawings. ## Deliverables The files will be provided in PDF format, they are currently in paper form. No changes to the prints are needed, I simply want to convert them from paper into Autocad. Files will be of similar or lessor complexity to the enclosed attachment.
