We appreciate the suggestion, but we have no way to handle orders involving recurring payments at the moment and, indeed, PayPal may not even provide any way of integrating those into an outside e-commerce system such as ours.
As far as we know, all solutions using PayPal Recurring Payments system are just using PayPal's own solutions for those as-is; you might want to hire a custom development shop to investigate the possibilities of using that system.
Even our own subscription plans for the use of our services just use PayPal's solution, but it's one thing for our own, tailor-made and dedicated account-management system to simply passively receive notification of payments so we can keep a seller's account with us active, vs. entirely another matter to build a system from scratch that could be flexible and usable enough to support the myriad of things a merchant might conceivably want to do with recurring payments -- that's frankly just a massive undertaking, and not likely to happen soon with us, if ever.
We can see if there might be any way to use our cart to take the initial order that would start a recurring-payments schedule, but there would be no way for our system to do anything at all for any subsequent auto-recurring payments.
