Refurbing/cleaning used multiair unit

[bookgrub]

I've got a multiair unit from a 2010 MiTo sport. Did about 38,000 before replacing it - turns out it wasn't faulty after all, and the ECU was playing up. I've had it well stored since, and finally getting around to doing something with it.

So, is there anyone in Australia who'd be recommended for taking it and giving it a good enough clean to be of use to anyone wanting a used unit, or to be a viable spare for my own car? Not sure where to look for that sort of service.
