Re: How to become an aikido instructor in Egypt?
Use the dojo search feature on this web site. You will find 9 dojo in Egypt and 7 in Cairo. Ask one or all of them what they suggest.
Probably easier to give Rob L. the $500 and take that advice. Cairo is pretty big so find a location far removed from the other established dojos just to minimize the 'cramp' factor.
Of course, one can go 'old school' and storm an existing dojo and just move in and take over (irimi and control the center).
