Timney trigger for Arisaka

I have a sporterized type 99 Arisaka that I plan on using on a hunt up in Maine this next fall. I have some more work to do on getting the scope dialed in on the s&k mount that's installed , but the trigger will be the next on my list . I know Timney makes a trigger that seems to be pretty straight forward but I think I'd rather leave that up to someone much more qualified than me. There is a little opening of the sear slot that needs to be done , and I know I can mess that up really fast .

any suggestions on who ? I'm located near Fort Dix , I plan on stopping by sportsman center this week and asking them , just figured I would throw it out here before I go to them.

Thanks for any help in advance .
