Customer Order Form Paypal Integration

Hi all, I have a website that people order daylilies from online. Basically what I need is a order form that captures users information. Then gives the customer 3 payment options: 1) Order through paypals website. 2) Order via check. 3) Order through our website, using paypal integration (website payments pro, where the user never leaves our site). The site needs to get a notification back from paypal when a order is successful, to mark the order completed. Email the customer a receipt/confirmation, and update inventory. I will give you ftp access, and access to a testing database, where you can setup a test environment. Payment via GAF escrow only. Preferred budget $350-$400. Absolute max budget $500. Must be ready to start now and complete the project in a week. PM me for more details and website.
