VIrtuemart 1.5 function addon - Urgent!

I have a website that have fully developed and integrated with Joomla 1.5 and Virtuemart 1.1.8. But we want to add some additional function in the website and virtuemart administrator panel. We want 100% the same function that shown in this link ([login to view URL]). In the "Order Now" section, you may choose to print for "letter" or "number" and fonts used, sized, materials...(the setting can be change in the panel) and integrated with Virtuemart so that it can use the checkout function. I need it very urgent and only for serious bidders....because we will working in long-term for almost most of our projects programming. I need someone that can meet the timeline because we always work in short time of period. thanks.
