Looking for good alarm installer in L.A. area

[Sil2000]

Hey everybody, like the title says I'm looking for a good alarm installer in the Los Angeles area. I have a Clifford RSX 3.5 that I want to get installed into my 2000 chevy silverado. In addition to the alarm I have also purchased 3 piezo sirens, tilt sensor, glass break sensor, battery back-up,and I also have the bypass module. There are just too many stereo shops around here and a lot of them are either shady or incompetent. This is why I come asking for your help. Any recomendations will be greatly appreciated.
