String of dates to exclude weekends AND holidays

Hi all,
I'm looking for a formula that will give me a string of any 60 business days (to be returned in row 1, columns A to BH) excluding weekends AND holidays.

I have a formula that will exclude weekends:

=if(WEEKDAY(A1)=6,A1+3,if(WEEKDAY(A1)=7,A1+2,A1+1))

And I have a formula that will exclude holidays (but not weekends):

=if(COUNTIF(Holidays,A1),A1+1,A1)

where 'Holidays' is a named range of the 11 market holidays between Christmas '08 and New Year's '10

I'm having trouble combining these such that my formula will exclude both and return only the next 60 'business' dates.

Any help would be greatly appreciated!

Thanks!
