Start saving hundreds of dollars from simply generating your own dedicated IPv4 proxies. These scripts are written using the API of various data center companies to automate the installation of squid. These scripts come with various configuration options, such as, user:pass or IP authentication. Edit the config file to fit your authentication needs.
Only use what you need. Your proxies are created when you please, and deleted when you please. Only pay these data center companies for what you need! This beats long term plans with proxy companies - giving the power to you.More Info
