need working US proxy

I am looking for a working US proxy so I can check my US offers. I tried the free ones and they are crap.

Willing to pay if I have to.

I'm running a http://www.seo-proxies.com if you want an exclusive US proxy, you should check my http://www.blackhatworld.com/blackhat-seo/proxies-sale/107493-new-exclusive-http-proxy-service-api-multiple-subnets-auto-browser-configuration.html

Your proxy will be up fast and work as long as you stay subscribed.

If you've any questions just contact me or ask in my thread.
