I need a new website. I need you to design and build it. I need a someone who knows how to make a private chatting, calling, and video calling website. The website must come with a feature wherein members in a group can be ranked, each ranks have unique permissions and capabilities. There must be a separate website, app, or software for me to costumize the website myself. I shall be able to costumize the rank names, permissions and others. The app must look techy and "hacker" like. Sending pictures, videos and money must be allowed in the app. It doesn't have to look professional as long as i have the things I want in it. The web must be color black with texts and outlines color green or anything that will make it "hacker like". Make it the cheapest yet good not best.
