What you said makes sense, however this does not apply in the Middle East, I'm afraid.Anyone that calls themselves a " carpenter" should easily able to build one just with a picture or description.
I'll be getting mine completed this week and I'll send a picture here.
There are many ways to build them. Mine is simple and utilitarian
You certainly don't have to use my ideas.
But it will be done by Friday - I should be able to find the time.
