A couple of suggestions if you can't find anyone locally:
In the States: these guys in Portland Oregon seem to best reputation on tdiclub.com... guys from all over the lower 48 ship their injectors and pumps there:
http://dfispdx.com/ Haven't dealt with them personally, but most threads lead to them.
However, just a bit north of you in the Great White North are these guys:

Not affiliated with either, btw, but a happy customer of the guys in the Great White North.
