Ogone payment gateway for MarketPress and documentation

Firstly, I need a payment gateway for MarketPress ([login to view URL]) for Ogone ([login to view URL]). I will provide a working development environment with MarketPress installed and a Ogone test account. In addition, all Ogone documentation is available in English. Secondly, I need a documentation (a PDF document with images and annotation) explaining how Ogone must be configured to be used with the gateway. Requirements for the payment gateway module. The payment gateway must be configurable through MarketPress backend. The payment gateway must update order status (paid) in MarketPress backend, if the payment is confirmed by Ogone (i.e. transaction feedback). The gateway PHP file must include detailed documentation in the form of comments for troubleshooting MarketPress or Ogone issues. Deliverables: Ogone payment gateway PHP ready to be used with current MarketPress (version 2.5.9) with Documentation PDF detailing Ogone "Technical Setup" instructions to prepare Ogone for the use of the MarketPress gateway.
