Changes in C# application

Hello! I have an application written in C# used for placing orders. I need small additions to it. But need it to be done urgent 1- Currently the app is showing the daily sales report. I want it to be able to show monthly (just date and sum of sales with monthly sum at the end) and yearly (just month name and sum of sales for the month with yearly sum at the end). The MS Access queries are ready. 2- Add comment field to every product selected (should be as well shown at the invoice). 3- There is a field called delivery sector - it should be deleted. 4- Add a drivers table. So that the order can be assigned to a driver. And whenever needed one can select a driver and a date and get the list of assigned orders to a driver and sum. Also, there are orders that are not assigned to a user, so its not always the case. 5- Create a client to the system, whose data will not be able to be changed.
