Narrate my computing tutorials (1) - Operating Systems

I would like someone with a good narrator voice to read out my tutorial series. I have written up the first tutorial and I have attached in PDF form. It has instructions and I would like a good high quality copy of the narration so I can use it for my YouTube channel.

Please speak very clearly and present a friendly and professional introduction to this tutorial series. Warm up your voice and do not let your voice come across as boring, robotic like or unclear. Explain confidently, precisely and do not make any er, uh sounds or allow for long pauses. Allow it to flow fluently and to a professional standard. If your final recording is not 100% then restart until it sounds perfect. Provide humor if it is suitable and do not speak fast, keep it slow and understandable!

It is for a video tutorial series on Operating Systems. If good enough then you will be asked to do more work. I am using flash to animate the content with the voice over and there will be a mention of the narrators name at the beginning of the clip.

I will take full ownership of the tutorial video series. If you feel the language of the write up is bad or could do with amendments to sound better please let me know what needs changing.

Thanks
