Arduino Midi Synth module project

Hello forum I need someone to help me out with an Arduino project. I have an old Casio MT - 40 and I love the sounds it creates but don't like the action of the keyboard so I would like to use the chip set and add a midi port and essentially turn it into a midi synth module to be controlled with an external keyboard?

Can anyone out there help me? Please email and we can discuss a work order to make and program this?

Please email me for further information if you are interested. Will pay $
