Has anyone already integrated MyPOS to accept credit card payments? (more info below)

If anyone already has a ready-made solution for integrating a WSX5 made webshop and MyPOS - please let me know.

I need this for a friend who has a MyPOS device and now wants to integrate MyPOS credit card payments with his WSX5 website.

He'll pay for the ready-made solution and/or for installation/integration help - thanks!
