Nj shop suggestions?

Can anyone recommend a good shop to get my prg advanced coilover kit installed at in new Jersey, Eastern pa or on the NY/nj border? I called OK4wd which seemed to be popular and was told they don't install parts that are not purchased through them. I also called a shop called "the 4x4 place" and he tried to convince me that PRG products were not good quality because he has never heard of them which is not reassuring that the shop knows nissan well enough. So does anyone have a hidden gem shop to suggest? I am also open to the idea of paying someone with the legitimate know-how to install everything who lives within a reasonable distance. Thanks for any input ahead of time!
