Anonymous C Class IP Range Proxy

I need an exclusive/private proxy server setup. I need 20 Exclusive US IPs from different ip ranges. Fully authenticated (Username/Password Protected) of course, anonymous, 99% uptime and does not identify as a proxy. More ips may need to be added in the future and willing to pay for them, but need to know how much. The proxies do not identify themselves as proxies and need to be checked at Lagado's Proxy Test. The proxies do not send any identifying headers such as Via, Forwarded, X-Forwarded-For, Client-IP, or Cache-Control. The proxies need to appear to be a normal browser request. Tell me everything that needs to be done and your fee. Thank you.
