Add Functionality To Existing Store Web Site In Visual Studio

Hello, I am seriously looking for help with adding just a few things to my program. I am using Visual Studio And it’s written in ASP.NET. I’ve attached the program that you can open in visual studio as well. Step 1: Add a label below the cart in the “Cart” web form that shows the total cost of all items in the cart Step 2: Add a radio button in the "CheckOut" web form that adds 5% of the subtotal (total of items in cart) to the total order and displays it (see the Bill Of Sale Template below). Step 3: Change the form named "CheckOut2" to mimic the layout of the "Bill of Sale" I have attached below. Step 4: In the “CheckOut” web form make it where you can only choose either Visa, Master, American Express The website should provide a bill of sale for the customer that would include the customer’s information, Sales Tax (costs 10% of subtotal) and when the customer should expect the package to arrive at their address. Please see an example of Bill of Sale - attached. In the Bill of Sale template, everything in bold would be generated based on the information the user gives in "CheckOut" web form. SSN, Date of Birth, Credit Limit, can be removed from the "CheckOut" web form as well. Needs to be done by the end of the day today.
