Wherever you are in the world, you can earn money.
Recently, I was having a great time in Hanoi, Vietnam. If you're looking for a place for vacation without spending more than $250, I suggest you go to Hanoi. The people are very warm and friendly, and the place is unexpectedly tourist-friendly.
Back to the topic...
When I was in Vietnam, I was able to mix business with pleasure. The hotel I stayed in had a very strong wifi connection, so I didn't have difficulty checking my earnings everyday. I was also able to write some entries and promote some products in the evening.
The point is, if you're looking for a flexible way to make money -- one that you don't have to watch over 24/7, or one that you can take with you everywhere you go -- be an affiliate marketer.
With affiliate marketing, the world is your workplace!
NOTE:
Not all places are affiliate-friendly. For instance, in the United States, you can't be an Amazon affiliate if you live in California and some other states under Amazon's no-affiliate list.
Also, Paypal is not available in Pakistan.
