Report for Marketwise-Productwise Sales

Question

Hi,
Here is one of the requirements....sorry I tried to manage examples of report output but it is not showing properly in Preview...
A report is to be written for a customer, showing the Marketwise Productwise Sales for each Salesman. The requirements of the report are described below. A report writer tool like Crystal reports is not available due to the cost involved in its licenses.
1. Report should be sorted on Salesman’s name and Print a new page for each Salesman. Salesman can operate in more than one region and one region may have
more than one Salesman.
2. The page should contain Marketwise Productwise Sales as the rows and the Regions as columns. Maximum of 4 Regions can be there per salesman.
3. The Rows print subtotals on each Market Id and print accumulated total Sales Value at the bottom. But if there is only one product in a market, only one row is
to be printed without printing the subtotal. (e.g. Example shown below for “Market3”)
4. The column Total for All Regions also should be printed.
5. All Regions for that Salesman must appear in the columns irrespective of whether there is any sale for that Region.
6. The report should work without any code changes when two more Regions get added.
7. Product mapping with markets, have ENABLE_PRODUCT = “False” should be skipped from the report. This is the way to enable a product to be reported for a
market.
The example is shown below -
Salesman : Sales Man1 (Figures Rounded in Million Rs)     Page:1
          City_A City_B     City_C     City_D     Total
Market1     Product1     10     12     3     25
     Product2     11 11
Market1      SubTotal     21     12     3     0     36
Market2     Product1          5     5          10
     Product3               1          1
Market2     SubTotal     0     5     6     0     11
Market3     Product7     1     0     1     0     2
Total          22     17     10     0     49
Salesman : Sales Man 2      Page:2
City_A City_B     City_C     City_D     Total

Based on the above requirements specifications, if someone had already built this kind of simple report, can I have the pseudo code or logic to build this report..?
Thanks

A report writer tool like Crystal reports is not available due to the cost involved in its licenses.Do you think that Oracle Reports is free then? It's $$$$.
You can download and test it for free, but if you want to use it in production you have to buy a license.
