Drupal Commerce - New Recurring Payment System on an existing site

General information for the website: Business Directory
Kind of development: Customization of existing website
Num. of web pages/modules: 1
Description of every page/module: Hi, I have a Drupal website up and running with commerce and commerce node checkout which allows users to complete a node on a particular content type and when they save it, it takes them to a shopping cart where they pay a fee for a 1 month subscription through pay-pal, once the payment is complete the content is published, then after a month it emails them and then unpublishes the content.

I can also set this up to charge for different periods like 6 months or a year

.
Description of requirements/features: What i would like the site to do is to have a recurring payment set up where each calendar month it takes the same amount until the user specifically logs in and says not too.

I'm not new to Drupal but i don't have much experience of Drupal commerce. but i think it will hinge on Drupal commerce licence or recurring framework and card on file? I would prefer this to be done on existing modules if poss.

I can follow instruction and theory but can also provide access to the site if necessary

Extra notes: Open to negotiation on price, but this shouldn't take someone cleverer than me very long to explain or do.
