Thanks for the clarification!
But I think we an really work around all that you have duly stated for the purpose of clarity.
I also think you should discuss more with @SOMHO as she is the one present in Hargeisa and can information you need about the place and the people.
I will suggest we get information about the 15 learners and get o know them before going much further. This will help us do a background introduction of the criticality if the project and how important their earnest commitment is needed.
What footy think about doing a crowdfunding for this project or does the individual you mentioned ready to foot the bill whenever we are ready?
I am a mechanical engineering graduate, so I have some knowledge about FEM too but clearly not as deep as you but I am sure I will cope well with whatever you are trying to pass across.
I think we need to start putting things into documentation as to be able to generate a workable document when the time comes.
Looking forward to blowing this operation up as soon as possible.
