Paypal buy now form with sending emails - php

Question

I have a form that collects data on a persons car (year, color, class, last 4 digits of vin. That same form also has information on the person registering for this event.
When the user clicks the paypal buy now button it should send an email to the person who is accepting the forms as well as redirect the user to paypal so the user can pay the registration fee.
You will see a submit button as well as a buy now button. I basically want the functionality of the submit but the redirection to paypal like the buy now button. Also not sure what the action should be on the form.

I assume you will be store the data in a database. I recommend that first save your form data in the database, Once stored, create a checkout page by querying the database and creates the additional form of paypal. you will require documentation of ipn paypal for sending instant notifications.
