Where to rewire multifunction button for steering?

[Mouse]

Hi guys, can recommend some of the places which can do rewiring for E46 sport steering multifunction button (so that i can use all the button function). coz i understand that if we fit the steering only without proper rewiring of the multifunction button, it cannot be use. how much is the cost?
