Clone of AJAX card invitation site

I am looking for something that operates the same way as [login to view URL] I do not want it to look the exact same because I am not wanting to copy the look. We already have a Magento shopping cart with design done. We just need the card customization feature (I think the above site uses AJAX, prototype, jQuery, complex CSS, WYSIWYG editor, etc. Many technologies). Once you go to [login to view URL], click on the Personalize button and add some text, add some photos, and go through the check out process. See the different steps. Add the final product to your cart. You of course to not have to check out. You will see where it will ask you if you want to add coordinating products, etc. We will need an admin section where we can EASILY create the text box areas and photo areas on the cards, etc. We sell all sizes and shapes of card type products. ***MAKE SURE YOU THOROUGHLY REVIEW [login to view URL] BEFORE YOU BID. This site must be VERY professional. Needs to work just like [login to view URL]
