A few comments.

If the second link is what someone offered you as a solution, its as good as useless. You are looking for a planetary gear system and the image that was sent to you is a useless joke. Please realize that gears are very complicated geometry - something that simply looks like a triangular tooth will not mesh correctly.

You seem to be all over the place in terms of what you are looking for. In the first post you are asking for 20:1 or more reduction, but then later on you show that you already have a 100:1 reduction. So why not just use the 100:1 if you are looking for the highest gear reduction possible? Are there other parameters you need to hit? Is there something more to this project you haven't mentioned?

What is your end goal? Are you looking to get this only designed? Are you looking to get it designed and 3D printed? What is your budget for this project? Where are you located?

If you are still looking for someone for this project, feel free to PM me with the info above. I take on side projects once in a while.
