For proxies id have to recommend myself http://osbot.org/forum/topic/68454-%E2%98%85%E2%98%85socks-5-proxy-shop%E2%98%85%E2%98%855%E2%98%85%E2%98%85lifetime-sponsor40fb%E2%98%85easygoldstop%E2%98%85best-price-guaranteeppskrill07rs3-gp/ my proxies are very safe and not flagged or blacklisted users have bought proxies from me and still no problem or bans.
As for VPS's I sell them also but they are unmanaged meaning you would have to connect through SSH and then to a VNC if you know how to do that. In that case my proxies come from the same place my unmanaged servers come from and both are very safe to use. They are based out of downtown Kentucky.
