How To Calculate future dates from start date on a monthly cycle

I'm trying to combine monthly calculations with "today" and with "workdays"


Example:

start date = 01/01/2009

today's date 09/16/2009

formula result = 10/01/2009 ; or if 10/01/2009 is a Sunday, result = 09/29/2009 (not 02/01/2009, 03/01/2009, etc)

=edate gives me a month but it doesn't skip weekends or calculate beyond today's date
