Record One 4 Minute Video - Simple and Quick

I have a 500 word article I have converted to a powerpoint presentation. I have gone through and put the presentation together. I just simply need someone with a half way decent microphone and a basic command of the English language - some accent is okay, but nothing too strong - to read the article/powerpoint presentation. It consists of about 35 slides and literally if you make no mistakes whatsoever in the live recording of the presentation, this can take you 4-5 minutes of actual work. If you goof a bit, you'll need to go in and edit that part out. As far as that, that's it. This project couldn't be any more drop dead simple for someone who knows what they are doing and who has done this before. After that all I need the video is to be produced in normal 640x480 - whatever the standard spec is. The video needs to be saved in wmv format. I don't care about getting the camtasia recording files back at all. All I need is the wmv - the final product. The video probably won't be any more than 10-20 megabytes maximum. I will provide an example of a video I personally just completed in about 10 minutes time - and that included editing. This is a quick and easy project for someone with even basic video skills and who knows what they are doing.
