cart integration with temando system

Hi - we are looking at integrating a cart into our website. Currently we use Paypal and our own payment gateway but nothing is austomated with regards to the order tracking, printing invoices and printing shipping labels. We want you to use either Magento community & Joomla (virtuemart) and it is then to be integrated with the shipping brokers www.temando.com.au. Our web site is www.ripsnore.com.au. The live site is NOT to be touched at any stage as it is fully operational. No time wasters or people who reply and then cannot do this (you know who you are, but not going to be racist) regards, Dave [login to view URL]
