Small .Net Proxy App - socks5

I need a small .NET application that : - Scrapes socks5 resources online to bring/check consistantly new proxies. could use script like this [login to view URL] or any other url added. - Should allow use of IP:PORT:U:P for Private proxies - Allows to add new proxies manually or through upload (txt) - on Main Interface, Makes a list of all the working US Socks proxies and only displays: IP / City/State / Online Status /USE - USE Button to PUT/INject Choosen/Selected Proxy/(ies) into Firefox as socks5 proxy App needs to be efficient & Fast. Don't need to have all the details about a particular proxy besides what's required. All the work needs to be done in the background. Multithreaded for speed and extremely stable Compatible with Windows 2003 Just need to be using a working proxy from a selected city and state in the US at any given time. All other proxies from Other countries, Non working proxies, Non Socks5, BlackListed etc.; Should be Filtered out So I have a Clean list to use. Short and Simple ex : An Imported list of [login to view URL] [login to view URL] [login to view URL] Will be handled and come back listed in the App as IP CITY STATE STATUS SELECT [login to view URL] Los Angeles CA OK O [login to view URL] Chicago IL OK O All the bad ones will not be listed. Need an Expert in .NET Proxies, Windows that can do this well and fast. PMB for any questions.
