Country/Location wise Ads/Classifieds

Hi Friends,

I did my best to search the forums in order to learn ,if i can do what i am willing.
I mean if it's possible to see the Ads(classifieds) location based? so that people from sprcific location or country can only click their country and see the ads or jobs in their area?
like USA , Canada, Italy, Pakistan, Spain etc  ? if some one click Spain that use can see ads only in Spain etc.

something like this www.JobsHawk.com   its just an example to to understand what i want.

Please show me the direction to that i can get it done. Thanks in Advance

Any Help here please?

This was one of my original requests to my first 'agent' actually. He said his team would 'consider it' as it would be a significant amount of work... but not impossible. They never did get back to me with a quote so I guess he considered it not viable. It's not a standard feature and almost certainly requires some modification by a decent programmer. My other idea was to have all content only available to whatever country the member was in. Again, apparently deemed too complex. Good luck!
