Need exclusive anonymous http proxy service

I need someone who can set up a exclusive/private proxy server. How do I go about it and manage it monthly. 500-1000 Exclusive non US IPs from different ip ranges. Fully authenticated (Username/Password Protected), 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 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. Please tell me everything that needs to be done, the initial setup fee and the monthly fee after. Also show let me know what your rate is the manage it monthly. ***These need to be NEW proxies - never been used before.*** The IP addresses MUST be located in any country other than Canada or the United States.
