I need a small system that has these features:
-An input form to enter a domain name, if the domain is available (a little whois in php is needed) leads to a payment on paypal, else the user are redirect to a page that says "Error".
-If payment is successful, the system will create a user, the username of this user will be paypal email address or a username in this form: "[url removed, login to view]".
The password will be generated occur randomly. This username and password will be sent to the customer by email.
-If the payment isn't successful the user will be redirected to a page that says "Payment Error".
-After the payment will appear a blank page (which I'm going to edit).
-Everything DO NOT need to have a graphical interface (only basic HTML form. The Emails will be in simple text format (only username\npassword)).
-Will I have the opportunity to configure settings such as: basic paypal account details (such as API key), sale price (for paypal), username and password of the database
-All Payments and users will be stored in a database.
