Have a PDF that was generated from Microsoft Project a few months ago, but have lost touch with the originator and need it converted back into Project with a few small modifications.

Modifications are all timing - just moving some elements back a few weeks. No new tasks added.

Should be pretty simple if you know Microsoft Project.

As output I will require both the MPP file and a PDF version.

Project will be two short phases - first just turn around the attached PDF as MPP, then I'll tell you the few changes required.
