Need Proxy Recommendation - Just one City Specific but Rotating

Looking for a proxy server that I can subscribe to that is city specific (Seattle, WA USA is one city I know I need for sure) and the proxy will rotate the IPs for that City automatically at some interval (could be once a day, prefer a little more frequent) Low cost. Decent anonymity preferably something Google doesn't detect and keep asking for ReCapture image verify. Any recommendations would be greatly appreciated.
