F10 Markaz - A few shops do it but they are unprofessional with big claims and crappy work. They use Chinese sheets which they sell for the same price as Infinity and Caliber sheets but get the job done
Disco Music Blue Area - Havn't installed anything from them but they had CV sheets for 2.5k each. Thats a bit steep
Sound Valley Pindi Saddar - Good stock, very professional ( owner is a member here and has done some crazy ICE installs )
I do most of the sound deadening myself because it's not that hard to do. I've mentioned this in quite a few threads now so this info should be easily found
