Joomla - Inphonex Integration

Hello, We are looking to have a module developed that will integrate our Joomla website with an existing vendor interface based on the api documentation listed here: [login to view URL] The requirements are as follows: - Integrate the Joomla Sign-up process to store new user information and create an account on the vendor site - Integrate the account financial (renewal and package) information so it is controlled by the Joomla Site - Allow the customer to make payments on their account through our online store and [login to view URL] - allow all functionality available through the vendor's api as if it was our own Thank You
