geolocation script needed

Job ID: 33431339

Budget: $30 – $250 USD

I'm looking for a script that can locate where is pc/mobile/tablet device is located.
This to personalize the content based on the location of the user.

It should work as a stand alone script which can be linked to all other kind of api's of products and so on.
This must be easy to implement for new scripts/products i wanna develop.

One of the issues that you get the location of the ISP must be solved, for example at ipinfo.io i get to see i'm from a province in NL which is 100 miles from my real location. The ISP i use is located there, but i'm not.
so that kind of tools don't work.
