Edit a camera phone video to include the presentation

Presentation is approx 1 hour long in total and needs:

Introduction
Musical background (select from non copyright source)
Editing to remove sections of the presentation not relevant (I can provide times to cut)
Add the power point slides as I am talking
Add any graphical text as required.

I can provide more details on the exact edit once the presentation is completed on Friday (edit required on Sat/Sun/Mon for prompt distribution of the video.
