1. Go to Google
2. Search for anything like "lol" for example
3. Below the search bar there should be something called a "Search Tool"
4. Click on it and it will give you searching options which you can alter.
However, when I want to search in a specific location like the West Coast I type in "Bay Area, plumbers" or something like that. Now my results will be centered around the Bay Area. Similarly "Eastern US jewelers" or whatever you are searching for.
For best results try and localize the search as much as you can.
