Using Excel 2007

I want to do a sumproduct where one of the conditions is that "Dedicated" is
NOT present in C:C. Dedicated can appear anywhere in the text and the text
varies, so I am using a FIND.

I am not sure how to do this? Here was my quess...

=SUMPRODUCT((A:A="GOLDMAN")*(B:B=1)*(FIND(C:C<"De dicated)))

Thanks,
