I need a social media style app developing

I need a design for a social media style app. The app will be a platform for users on a subscription model to access with the addition of a business subscription. The users will not be allowed to post only the businesses signed up with permission to post.

There will be multiple feeds per category for example if somebody selects the category hotels, only posts from this particular category will show and will be the same for multiple categories but will also need an ‘all’ feed.

Look forward to hearing from you
