Build a Simple Website - Terminal Style

Hi! I am looking for a website developer to make me a very simple website! I'd like to have a website that looks like this: [login to view URL] or [login to view URL] But bigger fonts and also it works to enter commands. Commands then processed to another script that can generate output. Must be easy to add new commands! Style can look just like black-white or something like this [login to view URL] Low budget, just a fun project I'd like done for my own personal site.
