We don't do VPN services (yet) but for your own use I can set up Squid proxy server with basic authentication for you on an OpenVZ machine with your own private IP, rdns and root acess at
XenLayer.com. Our services are fully managed so something like this would be free of charge. If your fast you can pick up an $8.95 account at 75% off for the first month using the coupon JULYVPS75%OFF (valid in July only) - I can deploy you a VPS today.
