Ms Visio training

Hi
I'm looking for an expert in MS Visio 2007 and 2010 to prepare training videos. I will give access to all the required softwares to perform the screen recording. You will be basically starting from the fundamentals and going through the most advanced techniques and then finally showing few examples. You will have to be very clear and precise in explaining assuming that the person who is viewing them has no prior knowledge of MS VISIO.

I budgeted £120 assuming around 6 hours of recording .

Thanks
