Modify An Advanced Reporting Extension in Magento

[login to view URL] is an established on-line retailer. We have recently switched to Magento Community version 1.7.0.2. We require some reports that do not come standard with Magento. We are purchasing an extension by a company called Aheadworks. It is an advanced reporting extension that is 100% open source. We need the extension code modified to create the two reports. Below is a link to the extension. [login to view URL] General requirements for both reports are as follows: · The reports shall be capable of being generated independent of each other · The reports shall be exportable in CSV format · The reports shall be built as a modification to the aheadWorks Advanced Reporting extension for Magento Community which is an open source extension · The reporting period for each report shall be selectable · The reports shall each be capable of accommodating a minimum of 10,000 skus · The reports shall each be capable of accommodating a minimum of 600 orders per day with an average of 3 items per order. · The data required for each report is shown below. Most of the above comes standard with the extension. Anything that does not will need to be added. Report One: Sales Report You will be modifying the existing "Sales Report" that comes with this extension to add in extra columns and features. Report Two: Sales Sku Ranking Report You will be duplicating the "Sales Report" to create the SKU ranking report with additional modifications. Need this done within 5 days if possible
