PHP developer for BoxBilling integration with impresspages

I am currently building a website builder service using the [login to view URL] multi-site CMS - basically, users can create and edit their own websites. The system as it stands allows monthly payment by paypal as it's only subscription model and virtually no client admin features. It only supports sub-domain website creation without manual intervention. I am looking for a admin system that will fully integrate with impresspages to: I am looking for a php developer to integrate the box billing API with impresspages cms which is running a website builders service. I can't find anyone who has done this before so expect a certain learning curve. I may also will need a few other customisations to the impresspages CMS which is installed on it's own linux VPS. In a nutshell: I need users to be able to order subscription plans (for the website builder) domains and other services Domains and plans to be provisioned on the server Act as the admin panel - basically do all the good stuff boxbilling does (this can be in boxbilling - I don't need this integrated in the CMS pages, just accessible from a clients login) I am only after good php developers with API and integration experience. YOU MUST PROVIDE EXAMPLES OF THIS KIND OF WORK. And I mean an explanation, not just sending a long list of websites. If you do that I will not even bother responding.
