Create a deployment for my /25 IP Proxy Server

Hello, I am in need of a deployment for my CentOS 7 Proxy Server. It has 128 IPs and I need a proper configuration including authentication on username and password. One of the options must be to be able to quickly create a user and a pass, and give them access to X amount of proxies/IPs, and be able to set the durability of the acces (for example give access for 5 days). I want premium proxies, not sharing IP’s between users. Only if a multi port configuration is possible, that should do. Also, if you are familiar with proxies. We need a method to prevent or proxies from being banned quickly, such as an extra IP to prevent banning. I think this is a $50~ task. If not, please provide me with information.
