Best model for revenue? Traffic: 150 uv/day, niche: youth, user demo: mainly from Pakistan

Hello,
I have a blog that revolves around youth issues. I mostly write about socio-political and academic issues. The blog gets about 150 unique visitors per day and a huge chunk of them (about 90%) are from search engines (mainly Google). I mainly rely upon Adsense to generate revenues but these revenues are so petite that I'd rather deliberately get my self banned using Adsense . I understand that the keywords might have low CPC, and most of the visitors are from 3rd world countries, hence the low revenue.
Since some of my articles rank no.1 for keywords, and I've done a lot of work on the blog, I have one simple enough question: Is there a way to earn $100-$500 per month from the blog. I understand that affiliate products might not be the best way to go since the audience are based mainly in Pakistan so advertising might be my only way to make money. Adsense generates $5 dollars per month which isn't significant at all. :confused:
I am pondering over the options to generate a significant income from the blog. I've CPM advertisement in mind as well as selling links on some of my article and category pages. 2 articles have a Page rank of 3 while others have PR1. Most of the category pages have PR1 while one has a PR2.

What model would suit me the best? (If there is any)
Can I generate a revenue of $100 with current traffic?

Share your thoughts and opinions. I would honestly appreciate it. Thanks in advance.

P.S: I've searched through the forum to find a relevant thread to post my questions but couldn't find one.
