Okay, let me start by saying I am a project manager not an CAD specialist.  We are implementing a new CAFM system.  We are converting Visio drawings to AutoCad and verify the data lost in the conversion and do the polylining.  I am trying to do an est. for the project plan.  Can anyone tell me::

1. Is there a rough estimate on the time putting in a drawing for an office floor (polylining, quality control).  
2.  Is there a rough estimate for how long or how many sq. ft can be done.
3. We will be doing approx 3,000 to 4,000 sq ft avg floors.  We will be doing hallways, common areas, cubicles, restoom, offices, and break rooms.  We will not be doing port information, outlets, computers, printers, etc. at this time.

Thanks for any help it is very much appreciated.
