Write software to create reports and send to customers

I am creating a website which allows people to purchase investment reports. [login to view URL] When you go to the box and enter AAPL, the stocks that match the criteria will appear in the drop down. When customers select the stock (in this example it is Apple Computer), I would like an instruction to be sent to my server hosted with Amazon Web Services. In the Amazon location, there is an excel file ([login to view URL]) which will be launched. Then the stock code (i.e. AAPL) is to be keyed into cell A2. The whole excel file will update itself with external links depending on what code is keyed into cell A2. For this example, I have simplified it so that only three items (in red) change depending on whether the stock bought is AAPL or ABT. Different stock code will cause different numbers to be updated and the graph to look differently. (In this excel file I only have one graph but in reality there will be many.) After inputing stock code into cell A2, the next thing I want to do is to print the current Sheet in pdf with the name found in the cart page [login to view URL] (In this example the file name will be ProThinker Stock Report for APPLE-INC-4849”. After that the report is to be emailed to the customer who would have entered his email into this page [login to view URL] If he has bought multiple reports, he will receive an individual email for each report.
