Geo-targeted Content testing

I have done many different searches on Google to try and find something, but I am not even coming close. So I thought I would ask here.

Is there any way that I can test my sites on a state level? I have some geo-targeted content that is targeted to specific states in America and I would like to be able to test and make sure it is working correctly but all I can find are online testing websites that only offer either country level support, or at most they offer a few specific cities in the United States. The testers that offer the cities would work, however not all states are on the list.

Thanks in advance for any help.

Side note, I don't have to use a website to test. I am ok with using a browser plugin if there is one that works.
