Hi !I know you said you don't want to pay someone for smg you could learn with your friends. Still, when I was in Cairo 2 years ago, I had an excellent teacher. You can e-mail her if you want at ahemy@hotmail.com and tell her that I (ambera12@hotmail.com) gave you her mail.
Maybe if you don't want to take courses, just e-mail her and ask her for advice, I'm sure she'd help.
