Count Days In Specified Month

I am using the following array to determine the total dollar of contracts reviewed in one month.

=SUMPRODUCT(($C$5:$C$3002>$H18)*($C$5:$C$3002<$I18)*(D$5:D$3002))

Column C has the actual Date
Column H the beginning of the month
Column I the end of the month and
Column D the dollar amount

Now I would like to count the number of contracts that fall in the following categories in a given month. The minimum number is in Column N and the maximum in Column O.
1-499,999
500,000-2,499,999
2,500,000-4,999,999
5,000,000-12,499,999
12,500,000-24,999,999
25,000,000-64,999,999
65,000,000+

I can get the count for each category but am having difficulty with the count in the specific month. Does any one have any suggestions - other than a pivot table?

I am attaching a small sample.
