R92 trigger work

Picked up a Rossi 92 Win clone, and am extremely pleased with it. Drilled/tapped the tang for a sight, it's short, light, handy, and I can whack a tie plate at 85 yards off my hind legs.

Issue is the trigger. Not afraid to tackle many things, but a little flummoxed by the 92. Most how-to detail strip videos want to take everything apart; I just need access to the hammer.
Open to suggestions:
-Is there a shop that specializes in such work? Someplace in Westsylvania would be a help.
-Any link to a video that focuses on just the hammer, rather than taking other things apart?
-Does anyone offer a prepped hammer for installation?

Been trying to bide my time on this, and need some suggestions.
Thnx,
Moon

Sent Steve's Gunz an E-mail; have done some business with him before.
Laughed at the "...notorious...long distance cartridge fling..." I shoot mine from the porch at camp, and have gotten it down to a science landing the empties on the floor. They are too big to fall thru' the cracks.
Really happy with the slickness of the action; the trigger is really my only complaint.
Mine is a 16" in .45 Colt; really love the thing for its weight and handiness. It's really lively in the hands.
