PayPal payments pro

I'm falling behind on some projects and need some help... I need to get PayPal website payment PRO set up on a site. I's a very simple one page thing. The price will always be $495.00, so this should be easy for anyone who has experience in this area. Here's the process that needs to occur: 1. User requests to reserve a real estate property. 2. User agrees to Terms & Condtions. 3. User pays $495.00 reservation fee using PayPal Pro. 4. On successful payment, email notification send and property marked as reserved. 5. On error, user is given appropriate error message. Notification email sent to webmaster. Basically, all I need is step 3. Just leave and if/else in there for me to do my thing on success/failure. Thanks for bidding.
