Modify WordPress WP TimeSheets Plugin

We need a php/wordpress developer to modify a sql query and some php code within the WP TimeSheets Plugin in order to view a Report on screen and in excel format for:
1. All contractors
2. Specific period as entered by administrator
3. Detailed list
4. On screen and as excel download

Almost all the work has been done already we just need someone to refine the existing sql query and speadsheet formatting for us as we need the time data ie. in:08:00 out: 17:00 displayed on one row under the correct Day ie, Monday, per contractor as at the moment its displays in many rows for a contractor.See attached screenshot.

The usual WordPress users has been modified and is used for the contractor information with a couple additional fields like the Bill rate (using the User Meta Manager plugin). See attached screenshot)
The timesheet data is filled in by the WordPress administrator in the Manage Timedata area on a daily basis. See attached screenshot.

Attached is also the current format of the excel timesheet which needs to be modified to display the data in one row per contractor with timedata from Monday to Sunday.

We have more work on this project once the above is been done that we would then like to use the same developer for.
