Date caluclator to exclude weekends

I have a spreadsheet that calculates a future date based on a fixed start date, by inserting the number of weeks you would like it to project.

I.e

Start Date: 01/01/2011 (Saturday)
No Weeks: 14
End Date: 09/04/2011 (Saturday)

I use this to arrange appraisal interviews.

Now if someone starts work for us on either a Saturday or Sunday, the calculation will naturally show a Saturday or Sunday date, however many weeks into the future.

We don’t interview at the weekends so Id like the calculator to show the first Monday date following a Saturday or Sunday. In this example it would be 11/04/2011. Also if the formula could display the Day of the week that would be better, i.e Monday 11/04/2011

Can any one help.

Sample sheet attached.
