Modifications To Quote Engine Website

I have a website which you register on and then can view a comparison table. You can then select products from the comparison table to receive quotes on. I need some changes making to my website: 1) A welcome email is sent out whenever a customer registers on the site. We would like this email to have a PDF attached to it. We have designed the PDF. All we need you to do it make it so the PDF is attached. 2) Also on the comparison table we would like to add a Buy It Now button to each product. On each product there is a check box. Under the check box we would like to add the buy it now button. If this is clicked instead of the check box it will take the user through to [login to view URL] which is the confirmation page you go to when you click Get Quotes on the comparison table page. Any users that register and then click the buy it now buttons should then appear in the Customer Registrations Page / Admin and Qualify Leads Page / Admin in the could purple. Also the email that is sent out to the administrator email address should also state in the subject line “Buy It Now – Vehicle Tracking”. If it is a registration then the email sent out to the administrators should stay the same as it is now.
