PHP Runner trial site to be redone

I need a site done in PHPRunner to be redone outside of that framework. Basically the current site can functions as a the prototype of what i need and I can provide a login Preferably a larger public framework with a strict role/security component. The basic functionality of the application is a transaction system. A receipt is issued, currently this receipt is one single form, but i need it broken down in parts to add flexibility. So a one-step process becomes a multi-step process (3/4) The receipt can be transferred from one holder to another thats registered within the system The new site must be portable to a mobile device, currently the site works on a mobile device with a webbrowser but of course its not optimized. Together with the framework change, I need the layout to be simple and fresh, the current one is a simple template out of the box. I need this done in 3 weeks time, including testing. More details are available when I select a bidder.
