Sure a trigger job can be done by any gun smith worth his salt. Ask who your local gun shop uses if you don't know of any.

As for recoil, teo things come to mind. The first of down loading a touch and using 30-30 bullets. BUT be careful NOT to exceed published velocities for the 30-30 when using them. Its pretty easy to out class these bullets and very poor pref on game will result... My father learned this the hard way when he took to loading after a long time away and decided to use some Speer 150gr FP bullets in his 308 at about 2500fps... THE biggest racked buck stepped out in front of him and he shot and lost the deer.. later that week he shot a second buck and then a doe.. these bullets never exited and on the first buck all but came apart on the shoulder producing a devistating 2'' deep would, some shrapnel made it into the lungs and he was able to recover it...
Second, have that gun smith install a good modern recoil pad!!
