We need someone to create a fairly basic intranet for our company (we have approximately 50 employees) and we have an Enterprise account with MS One Drive.

Some of the features we’re looking for the following features:
–Calendar functionality that would remind users of important dates such as birthdays, events, or workiversaries
–A place where we can post our daily sales numbers (an image file)
–A place to house company photos
–the centralized place where ppl can post and others can comment. It would be a plus if it would allow users to comment back with gifs, emoji, images, etc as well.
–Search capabilities
–Allow users to post their photo and link their company information

We are essentially looking for something that is simple for our needs yet aesthetically pleasing and user friendly. We’d like the forum to encourage engagement.
