backend for a content calendar

Hello, I need a backend, hosted on a web.

The backend has user-management and roles.

- Such as Admins and Freelancers.

What the dashboard in the backend will be after login: 1.

is that it will show a list of articles/topics that will be published.

The table can be sorted and will have the following columns; Topic, Author, Agency, Date to be Published, Status 2.

The list of articles will be imported automatically from Google Sheets (the admins will configure this from specific URLs/sheets). 3.

From the main dash.

A freelancer can also post a topic and it will populate under the list of articles.

Thanks Conrad
