If you're not confident and good with a dremel and stones/cratex, send it to him for a great job and fast turnaround. He offers other accurizing services as well.
He has a great online video for the DIY trigger job which I followed to the "T"...very slowly and deliberately as this is something you can't eff up.
I ended up with a two pound trigger with only a hint of take-up and zero creep. It was used as a target gun, so I wanted a light trigger. You can adjust pull weight as you see fit doing the job.
