I've hired many a foreigner to work remotely, paying more than (USian) minimum wage. However, key here is comprehension of written English. (well, to work for me. And to work for me, you have to convince me that you are smarter than I am. I imagine those are different for other people.) I don't care about spoken English. Plenty of ways around that problem, I don't want to talk with you on the phone anyhow.
Of course, right now I have a huge number of options in my price range, so until more people catch on to this 'location doesn't matter' fact, he's got to get good before I will be interested. But there are many people willing to hire across borders.
Obviously, if he doesn't eat, that's his biggest problem. I don't have any good advice there. It sounds like you are up on the price/nutrition ratios of local foods. But to become a good nerd, he needs a computer. I remember my first computer. my dad gave me a giant book 'Upgrading and repairing PCs' by mark minasi. good book. he said read it, and he'd get me the parts for a computer. I did, I convinced him that I did, and a few weeks later the parts for a thoroughly obsolete (but completely loaded) 80286 were spread over my room when I got home from school one day. I mean, it was like '93 or '94, so even with the full megabyte of ram (it had a add-on ISA card) it was thoroughly obsolete. But it was mine, and I was able to get a shell account on a local BBS that had internet access. it was one of the formative events of my childhood.
Of course, I dono if it's possible to get 'free computers' in that part of the world. I mean, around here you spend some time looking in likely dumpsters and you will find some good stuff. (I have a friend who has a nice collection of obsolete RISC medium iron that he got out of dumpsters at the local university) I don't know how it is in Turkey.
I think learning how to be a support monkey is a very good first step (well, it's what I did first. And it was awesome. I remember I looked forward to getting out of school every day and going to work.) And it's usually an easy thing to get into, if you know a little bit and you are willing to work for menial wages. (my first job was fixing computers, but it paid maybe 80% of minimum wage.)
Of course, I don't know how much my experience applies. I grew up in America, and while my jeans came from the salvation army, and I've eaten my share of rice and beans, I've never had to worry about not having enough to eat. I do think that having a computer to take apart is important. Thinking of your computer as a 'black box' appliance is an expensive luxury.
