Thanks in advance for any advice!!!

I have a question about PHP code and Excel 2000 Templates. I am having a secure website built for my customers to log into and view order status, download quotes, etc... I have a pretty extensive quotation tool I have built in Excel 2000 that my customers can call in the spec on a building, I enter it while they are on the phone and give them a price over the phone. After that I generally print my summary page into a PDF and save the quote to there the customer file folder. I am having these folders with the phoned in quotes available for my cust to look at in the evening via our new web-site.

I would like to have a form on my website that they can enter the info in the evening and submit it in a way that will execute a code to open My Quotation Program in a Template form and input the info in the correct places. Then I would like for it to execute another set of code that will print a predefined summary in a PDF format to there download folder on my server.

Does this make sense?

And.... Is this possible?

Thanks
