Summary # of employees assigned to each task

I have employees assigned to jobs. Start date - End date.  As you can see I have a have a timeline report that breaks out each employee grouped by assignment and when they arrive and when they depart. 

I would like to turn this into an easy sheet to edit, upkeep and view.  

Weeks across the top / employees down the side grouped by task.  Check box for each week that they are assigned. 

I am at a loss of where to start.   Any help to get pointed in the right direction would be greatly appreciated.  

Thank you in advance for any assistance.
