Create an anonymous proxy server.

Hello, I am currently paying for proxies from all over the USA. I would rather own my own proxy servers like the following site does: [login to view URL] From what I understand, I just need to put some code on the web hosting server. However, I am not too familiar with this process or what is required which is why I come to freelancer. In a nutshell, I would like access to thousands of anonymous IPs that I can use myself or sell them.
