Google Adwords campaign

We have a Google Adwords campaign that was set up two years ago. Our monthly budget with Adwords is $150. Looking for an expert with Adwords that can review our campaign, suggest changes, and institute changes I recommend also.

One big thing that needs to change is that we are a "service business" and cover the whole state of Arizona. I believe currently Google is using our physical address and we only come up when people are close to our physical area. I need our ad to show up for people anywhere in the state not just people close to our physical address.
