WHMCS EU invoice templates - help!

Hi guys,

I've bought WHMCS and now I need help with an invoice template. I live in the Netherlands and Europe has some strict rules regarding creating invoices. I want to customize the invoice, but I'm afraid I can't. The invoicepdf.tpl file uses such a difficult language I can't understand. Does someone know a website where I can buy templates?

Please send me a pm if you can do it on our own, we'll discuss about the price. Thanks! :)
