I am using the latest version of Zen Cart and need to have a payment module created to work with the Optimal Payments system.
You can find details of Optimal Payments here:

You will need to have a good knowledge of how ZenCart works and also how the Optimal Payments API works in order to get this to work.
Payment will be on receipt of a working module.
I need this module created as soon as possible so shorter timescales would be prefered.
