Payment Gateway Integration CB Subs >> eWay

I have a Joomla website built with community builder and the CB plugin called "CB Subs" [login to view URL] This plugin allows paid subscription to the Joomla site. It comes with a plugin for payment gateway eWAY but the issues is that the gateway only allows for one off payments which is no good for subscription website as we need recurring payments. eWay is capable of recurring payments and has a very good developer API for integration. See here [login to view URL] I need a PHP developer to create a payment gateway for recurring eWay payments. For a skilled PHP developer it will not be too hard as they can see how the current integration works with the existing eWay single payments and then apply the new recurring payments to this. Or make a duplicate of this method and apply recurring payments functionality from the eWay API. All files in joomla and CB Subs are open source so you are not restricted. The successfull developer must really know PHP and Joomla structure to complete this job as I dont want to waste my time with a beginner trying to learn everything. Any examples of anything similar will get preference and to the successful developer who can do this job I will have much more PHP work going forward. Look forward to your reply
