Convert 5 PDFs to DWG Properly (AutoCAD)

I have 5 PDFs that need to be converted to AutoCAD and vectorized. They are originally from AutoCAD - so the conversion should be seamless. They must convert completely 100% without issue, and fully work in AutoCAD. **THE CONVERSION MUST BE MULTI LAYERED AND FULLY EDITABLE.** ^ THIS IS IMPORTANT. IF YOU IGNORE THIS, I WILL IGNORE YOUR BID. These drawings tend to have tons and tons of layers. I need to see that. I have provided you a sample PDF. Please attach your best conversion job possible with this PDF. Make it multi layered and fully editable. I will choose whoever does the BEST conversion job on my sample PDF. The sample is below: ==> [login to view URL] It's as simple as that. Anyone who has experience in doing this quickly and easily, please bid. That's it! Thanks.
