Oscommerce site. need custom email & order handling system

hello guys, i have an oscommernce website and i need custom admin?>orders page and an email handling system. I have installed helpdesk contribution (that is avaible for free on osc forum ), but it does not have all the features i need. For email system I am looking for features that [login to view URL] is using. And for my orders page ( where all the orders and customer details is dispalyed ) i am looking for features that selling manager pro has them. Its a program ebay uses to manage the sales and stuff.
