Looking for a great 4x4 mechanic (Camarillo)

I recently acquired a 2006 Chevy avalanche z71 from a friend of mine.
The engine runs and it drove fine for a while, even though it was sitting for a couple years! But the fourth time I drove it, there was a clunking noise that increased with acceleration and decreased with deceleration.
I could feel it beneath my feet and the pedals.
I think it might be the transmission or the axle but I'm not sure.
Need a honest and fairly priced mechanic that is mobile or one that is local to Camarillo.
I can have it towed if needed.
I would prefer it if this person had experience working on Chevy 1500s.
Recommendations are also greatly appreciated!
