Implementing a TPV for Zend Framework Site

This requirement is for somebody who know Zend Framework and can read spanish specifications. I need to implement a TPV (on line payment platform very used in Spain) for a web site developed with Zend Framework. This is a common TPV, it is part of Servired network, we can give support to implement it but because I haven't got time I am looking for someone to do it. Any question I am at your service. Thank you.
