If he (your client) is already having a paypal Website Payments Standard/Pro account, you dont have to register again.

If you want your customers make payments on your Site, you have to have a Website Payments Pro account. If you dont mind redirecting your user to PayPal site for payment processing, a Website Payments Standard account is enough. Check with your client which type of account he has.

After registering, there are few steps to configure your payment gateway (ref the first link on my previous reply).

You can configure your account to get an instant notification by IPN (Instant Payment Notification) callback after user makes payment. In IPN callback page, you can check the transaction status and based on the status (success/failure), you can decide what to do. 

Download code sample from the PayPal site (link provided on the previous reply) which will help you to integrate. 

You can create a PayPal Sandbox account to test your application (as if it is a live application).

Regarding different payment of amounts, you can pass any amount from your site to PayPal site through a variable.

thanks for reply
