CRE Loaded 6.2B2B one Page fast Checkout

would like to replace existing numerous checkout screens with simple one page checkout on a creloaded 6.2B2B. All I need on the one single page is : Name, address information (billing address /shipping address) side by side Shipping option Delivery selection Payment type selection (paypal or [login to view URL]) It has been done on oscommerce site , pls see the demo: [login to view URL] However this contribution needs to support certain creloaded functions “paypal pro” and “paypal IPN”.
