Socks5 Proxy need

I am looking for Socks5 proxy provider. Here is the criteria I need: - US, CA, Western Eroupe (other country may be consider) - It should be fast - It should be private - I need to test quality and amount of proxy before select you as provider. So you should give me test access for a couple of hours. I do nothing illegal - only SE parsing and account regestering. When bid tell me: - average amount of online socks5 proxies - socks5 list refresh period - you price for day or week or month access
