I would like my customers to be able to pay there invoices online with paypal I need a page to be added to my website and that maintains the look and feel of the site([url removed, login to view]). The customer should be able to enter there invoice number & the amount of the invoice. PayPal has a tool that spits out code that is very close to what I need but I would rather have something specific for my sites needs. Super Clean code is a must, good English is a pulse, and examples of PHP based paypal payment systems would help.

PHP Apache, I do NOT want this very simple program to have to access a mySQL-DB
