You can absolutely customize your LP depending on the user's location by using http://ipinfo.io, eg:

  $.get("http://ipinfo.io", function (response) {
      if(response.country == "US") display_us_message();
      else if(response.country == "TR") display_turkey_message();
      else display_generic_message();
  }, "jsonp");

I'll send you a mail to see if you're proposing something else.
