A little story:
a) An average Pakistani trying to get a job abroad without any links etc. he goes to dealer, pays amount for Visa other necessities etc.
Travels abroad- The dealer only covers the visa and stuff and optionally, extra payment for securing him a job.
When he reaches the destination- he tries to first find a roof over his head, even though he will have to share room with dozen of other men. After that, he starts the search for a job, desperate as is, he takes even the crappiest jobs just to keep living.
Slowly, he progresses and learns what to do, how to get a good job etc. This process can take days, months and for some people i know YEARS.
b) This person has friends/family living/working abroad- he contacts them, they ask their workplace to let another one in, telling them that he's hard working basically vouching for him. The workplace sends the person a visa and maybe a airline ticket too.
Apply online, once you strike go. Some people have sold their land etc. and wasted it all on living costs trying to secure a job.
If Milk costs 85-90 Rupees per liter in Islamabad, anyone with 8 lac cash can make 20-30,000 rupees PER DAY and that too in Pakistan.
