Peep sights for henry all weather

So I've been looking to get something along the lines of a skinner sight for the rear of my henry all weather but before going through the permit process etc I wondered whether there was any good machinists/gunsmiths in nz who might be interested in making something like this?
I have a scope base already if that is required for measuring up the receiver shape and mounting hole locations.
Would need to be slightly adjustable, at least for windage of course and preferably out of stainless steel.
Not looking for a freebie or anything like that but would rather spend my money on our own soil as a first option if anyone was interested or knew someone.
Cheers
George
