i saw a project very close to this a few months back, there are issues with the patent system and the laws are even harder to overcome! i dont have a good prospect for this project, so sorry guys but it is not a viable idea!
I agree, someone already tried this concept.
But to no avail, no success.
This is a tedious job to embark with, so much legalities and other documentary works to do.
It will be 48 years in the making. So not a good investment at all.
