T-SQL Dynamic Pivot table by Sunday Date only

I have a data set that looks like the following below in sample data. I need to break out the data as a summary of the data on a per week basis with the weekend ending on Sunday. I have tried various attempts at a dynamic pivot table but have had no success. Any thoughts or suggestions.

Sample Data

EmpID    ClientID   Contact_Date   Hrs
12000    1234         1/5/2015      1.67
12001    1235         1/6/2015      2.00
12002    1236         1/7/2015      4.00
....... 
etc

Desired Result

EmpID    ClientID   Wk 2/8/2015   Wk 2/1/2015  Wk 1/25/2015   Wk 1/18/2015 ....etc
12000      1234          4             3            2              0 

I have this query to GET Every Sunday within the date range of dates from all entries in the table with a certain status code.**

DECLARE  @StartDate     DATETIME
         ,@EndDate      DATETIME

SET @STARTDATE  = (SELECT MIN(contact_date) FROM dbo.vw_hrs_entered)
SET @ENDDATE    = (SELECT MAX(contact_date) FROM dbo.vw_hrs_entered)

SELECT *
FROM   (SELECT TOP ( datediff(DAY,@StartDate,@EndDate) + 1 )
                        [Date] = dateadd(DAY,ROW_NUMBER()
                  OVER(ORDER BY c1.name),
                  DATEADD(DD,-1,@StartDate))
        FROM   [master].[dbo].[spt_values] c1 ) x
WHERE  datepart(dw,[Date]) = 1

RETURNS
