2Checkout Instant Payment Notification needed

Hi everyone. I have the website Sale Age (dot) com which runs off a deposit withdraw system. So if you register and login and go to /[login to view URL] you see you can deposit money into your account. I need a Instant Payment Notification implemented with my 2Checkout (dot) com account. So when a user deposits and they are redirected back to the site the money will automatically be deposited in their account, instead of me having to manually add the money they deposited. To do this you should only need 1 file, the [login to view URL] file. I wont give out FTP info. I already wrote the MySQL_insert(); to add the deposit to the transaction log and I can help you with the database. Max I will pay is $30, this should take under an hour for anyone who has done a 2CO ipn before. If you have any questions feel free to ask.. this should be pretty simple and straightforward if you ever used the 2Checkout API before.
