Short Math Videos

I am planning to start a website on school level Math. It will have short Math videos, typically 3-4 minutes long, demonstrating an important Math concept or showing the solution to a Math problem. I have already created several of these short videos using Camtesia Studio and a free whiteboard software ([login to view URL]). I need someone speaking US English (important), well versed with the Camtesia Studio and digital whiteboard to recreate the videos. Please note that I will provide the problems/theory content and the way I want to explain the solution. No effort is required on this portion. All you need is watch my videos (unedited) and recreate the same (you can rephrase in your own words keeping the overall content the same). You need to use the arrow/line/highlight/etc hotkeys available in Camtesia Studio to make it interesting. Once done, produce each video in a standard format (say .avi) and upload to a server for me to download. No callout or any animation etc is required. This job requires the use of a digital pen tablet. If you are not having one you may want to just add narration by overwriting my voice in the videos I produce. Please bid accordingly. For the time being I want to get the job for around 150-160 videos. Once I get my partner of choice and the videos are liked by my visitors I have plans to create many more of them (my site is based on Math videos and I will keep producing them).
