53251 PHP Customise Script Needed

Hello, I need a either Mysql based backend script or a flat file backend. The script should work the following way 1) There must a one form where user fill out Such as Name Address Tel Phone Email # - Email should matches the Flat file or the Mysql database what ever you decided to use as backend. Once the Email Address matches it will take customer to the next page where they confirm the price and confirm the product & than next screen will take customer to Paypal Website where they can proces payments, Offcource my email address will be used in paypal so I will get payments, And the final page or a Thank you page should take them to my Main Page or my own created [login to view URL] file. In that Flat file or Mysql file the entry should like the following Email Product Name Price I assue I can manually add Email and Product name and Price via PHPMYadmin, let say if abc at [login to view URL] would like to process something Flat file or Mysqlfile has to match Email - Product name and Price. Next screen where they review the product and price and the 3rd screen will take them to the Paypal and Paypal will forward them to my Thank you page. Everything should be emailed to me such as Name : Product name Price Email Tel PS DONT BID OVER MY BUDGET, if you do than you are simply wasting your time. Thanks,
