Shopping Card / Ticket System with Paypal Subscription

Hello,
I?m selling SEO services and for new service I need some system with recurring paypal payment and ticket system. Client should choose from my site one of packages, pay via paypal (start paypal subscription) and in next step he should submit project details to ticket system.
Script should check after 30 days if subscription is still active or not, so we can know to continue SEO service or to stop it.
Is there something like this on the market ?
Many thanks!

I personaly dont know any module/script available to act this way but to implement it should be very easy because paypal sends an notification if subscription its closed so the only thing to check after 30 days its if paypal sent a notification to close the subscription.
