Build me an app and website

I am looking to create an interactive community online social app platform/website for our Synagogue in Cape Town. The ideas is that each member of the community can create their own profile on the platform with the ability to interact with other members. There will be a running feed as well where text, pics and videos can be posted. The app will have features such as a noticeboard with key communal information and a portal through which the current zoom services and lectures can be held. Other details will be discussed once a freelancer is appointed. We have a whole host of features that we would like to have on the platform, however, we will start with only a few of them, and with time hope to add on more features. These are the essential features: 1. Each member to create and control their own profile, and choose who 'sits on their bench' in other words who are their friends, like on facebook. There will be a feed where people can post 2. A communal noticeboard where communal information is posted such as times, and other important information for community members 3. a section that lists businesses and services of community members 4. All our online zoom services and lectures to be run through the platform 5. A children section moderated by our youth leaders where kids can play online games such as chess or backgammon etc The above is an overview of phase 1
