Authorize.net ARB integration w/ Virtuemart

I need to get [login to view URL]'s ARB functioning with Virtuemart. I have several products and a few need to be designated as ARB. This can be done in the background (no check boxes or anything like that needed on the frontend) as the product's page tells the customer that this is an ARB product. I also need to be able to designate a trial period for each product before it begins the ARB process. I may want a 2 week trial period before beginning ARB for the product on a monthly basis. I would prefer to have a checkbox on the admin side for each product to choose whether or not to designate as an ARB product. And also a checkbox/dropdown to select a trial period for each product. I would also need a way for the user to cancel their subscription through their online account.
