Rare Teterin Turbocharger.. who can do it up?

[xCalliba]

hey, rustling through the old mans shed today i uncovered an old turbo charger in pieces that once powered his 186 HR ute many, many years ago.
I dont know a great deal about turbo's, but i believe all the parts are here. An engineering company called Teterin Engineering use to cast these turbos, and i may be wrong, but used the Rajay turbo parts?

Anyways, just wondering who would have the knowledge and skill to overhaul this old beauty, and what sort of price could i possibly expect to pay for such a service?

I live near Shepparton (Vic), but id be willing to drive as far as Melbourne just for someone to have a look. Cheers
