Caustic did my Stella and CCM lever lock recently. He did a spot on anno match. He has also done my buddies Inception Kryptonite, a buddies Axe etc. You're in good hands with him.
Gruntbull is no longer in service from what I know. They might still be around but have heard some negative things from them. They initially did my American Psycho S6 for me back in 2009. I didn't have any issues with them then. Only took 4 weeks too.
