Autofill weekdays/skip weekends in a month

I would like to be able to auto fill weekdays (skipping Saturday & Sunday) in a month. For example, my spreadsheet would look like this if cell A1 contains12/01/09:



DATE WORKDAYS TASK

1-Dec 1 AP CLOSE - CAPITAL & POS ITEMS
1-Dec 1 POS MONTH END
1-Dec 1 HEALTH INSURANCE
2-Dec 2 DEPR SYSTEM RUN; INCL-SOFTWARE AMORT
2-Dec 2 SPECIAL EQUIPMENT
4-Dec 4 PRELIMINARY ENERGY REPORT
7-Dec 5 AP CLOSE - ALL OTHER ITEMS


The DATE column needs to return the date for WORKDAYS listed...Monday through Friday only. The first workday in Dec 2009 is 12/1, the fifth workday is 12/7, and so on...

Thanks!
