Another option is to consider Dan Killough, Killough Shooting Sports. He can provide a turn key solution getting all the components, over seeing the testing and tuning and providing ammo that's been matched to the rifle. Richard Gorham who's already been mentioned does his metal work.
Dan did a rifle for me and it's good.
Another Smith one needs to mention is Mark Penrod over in Indiana. He's a perfectionist and turns out some very nice rifles. He did the rifle for the ARA Nationals this year that they give away and it was a real nice.
