Require assistance in Integration of Task list + alert + calendar


Need your assistance in the following matter: 

1. Task list ( That contain tasks for multiple employees ) 

2. Automated reminder should go on task based that too the concerned employee

3. Need to configure "Task list", " Automated reminder" and Calendar (i.e. Google calendar) 

So technically, we want a single sheet that contain multiple tasks assigned to multiple employees having multiple due dates. Reminder should go to concerned employee occasionally as set. And all these task should be displayed on calendar. [ On calendar side, any attachment and ongoing conversation for that concerned task should be displayed ] 

Means, from calendar we can check development done for a concerned task with the help of attachment. 

You are requested to kindly tell us how to configure these functionality in our current plan. 

Look forward to hear from you.
