Slowchevy06

Hey guys I'm new here obviously I actually started this account to ask this question. I've been doing lots of reading on here about upgrading the cam and valves on my '06 L59 and also tuning it since the cam I'm looking at is a bit more aggressive. I'm not very comfortable monkeying with the newer computer controlled engines so I'm looking for a good shop to do that. Down the road I would also like to swap my 3.42's for 4.56's. I'm on the iron range of northern Minnesota and would prefer somewhere close, but I understand sometimes you have to travel for quality. Does anyone have any recommendations?
