121253 oscomm 2checkout modification

I have a client who moved their site to our server and there is a problem with the 2checkout module. I need a 2checkout module installed that does not collect credit card information on the client site but passes the total to 2checkout and returns to customer to the [login to view URL] page so that the order will be entered into the admin area for the site. I will need this done asap as this is a live site with traffic being directed to it.
