Add Credit Card form on Xcart Shopping Cart checkout page.

We are using xcart [login to view URL] and we migrating to another server. We need to configure it to allow credit card payment on the checkout page. Currently when you submit order it goes off site to [login to view URL] to process the credit card. WE DO NOT WANT THIS. We want to have everything on one page. Like this or similar [login to view URL]:One_page_checkout We are using xcart 4.5.3 We already posted a project for xcart tasks but who we hired couldn't do this job. We don't want to hire anyone that can't do this project. We want the cart to work like any normal cart and not go off site to either go to xpayments (xcart module) or the plain vanilla [login to view URL] site to run the credit card. WE WANT everything on one page. The checkout needs to work all within the domain and seemless. Here is where we could like to add the credit card form. [login to view URL]
