Drupal Commerce Payment Gateway Module

I need a payment gateway module for Peach Pay - [login to view URL] for Drupal commerce, Drupal 7. I am using commerce, commerce_license and commerce billing contributed modules to implement a Subscription payment plan on Drupal. I have setup these modules and have products such as STANDARD PLAN $20, PREMIUM PLAN $40. My payment gateway supports recurring billing for credit cards. So the Payment Gateway module needs to sync in such a way that it receives information each on month on whether a user has cancelled, the recurring payment has been successful etc. I see on the commerce license module the following: Remote licenses are synchronizable, allowing a remote service to be contacted each time the status changes (to create / suspend an account, or anything else). Remote licenses require Advanced queue (used for synchronization). So much of this code is already existing. Please let me know If you have experience with this kind of job and whether making sure the syncronization happens (and is well tested) is included in your quote. Thanks.
