Offline affiliate marketing is win-win, but in a cheap country it might be hard to pull off.

I know there are some issues with getting accepted for adsense in other countries. If you have problems, email me (profile link) and I'll give you one of the solutions.
1. Find a notepad. 2. Write: "Things I can teach you:" 3. List everything you imagine you can teach a person (This can range from simple math to programming to drawing to singing like an american idol?) 4. Hard part is over! Relax and decide on your mid-range topics (ones you're not a guru at, but with a little research could obviously teach someone) 5. Create little niche sites (google keyword tool -> show CPC -> Arrange by amount of hits (look in the 10k-20k views range -> google "keyword" (yeah quotes) -> if its less than 40k pages, and wikipedia is a top result, you probably just found a $9 investment (domain cost) that would turn into $20/mo. 6. Once you've spent 2 weeks doing this, you should have a feel for the idea and what grasps people's attention etc. Try some of your more guruish topics. Hell, make an ebook and offer it on one of your adsense sites.

<translations>You said cheap country, but I don't really understand the scope of that... but I'm going to assume you know another language. If so, start a site offering translation services or just scope out people. iPhone apps, etc need translations and shell out serious cash for them.</trans>

One final bit: when you research (blogs/sites) you will probably stumble upon keywords like 'mesothelioma, structured settlements, annuity payments, criminal lawyers, tax attorneys, asbestos, etc,' being the gold mines. Don't waste your time. $40/clk($5-15 your share) sounds amazing, but its another losing game trying to get ranked in search engines.
