193436 PayPal Integration

Looking to have PayPal integrated into existing custom made PHP/MySQL based application. How the script currently operates: A user elects to make a purchase. His purchase details are stored in MySQL. The user is emailed a confirmation email of his purchase, and is provided with a link to click, which takes him to my invoicing page. From this page, the user is given his total amount due, and provided with a link to make payment. From here, is where you take over. We have the following data to work with, already in DB: Buyers PP address Amount Due Description of Purchase Invoice Number When the payment is completed, the IPN should come back, and we will then update the DB record accordingly, with: Date Paid Amount Paid Transaction ID Pretty simple, nothing overly special. Terms: Winning bidder should be able to commence work immediately and finish in a timely manner, within the deadline specified at the time of the bid. If your feedback is LESS than mine, there will be no escrow, payment will be made upon completion of successful test. If your feedback is MORE than mine, there will be a 50% escrow made, with remainder paid upon successful completion. Happy Bidding!
