web development full stack

I would like to create a web app that is used for "virtual coaching." This allows two people to prepare for video or phone conversations by logging into the web app and creating an agenda and coaching log. While on a phone or video call the log can be edited and updated along with a special place for notes and action items. Some of the functionality will include sending out automatic email reminders for appointments, archiving checklist and action items, permission levels for coaches of coaches to view. The best example of something similar is in these videos. If you are serious about bidding on this project please watch all videos as this gives a great example of the scope and function.

Once I give specifics on functionality, how long do you expect it would take to develop this? What challenges do you forsee with this project?
