Edit together video recordings of a business presentation

There are three recordings of a recent business presentation I made totalling about an hour and a half. the first clip was recorded with the iPhone the wrong way round so the recording will need to be rotated 90 degrees. I would also like all audio enhanced if possible. An introduction clip and end clip need to be added. 17 out takes are required and remove any recording of personal names.

The recordings and notes can be found here
