Auto shop for blind spot monitoring system installation?

I have an older car I'd like to have retrofitted with a blind spot monitoring system. So far, I have found Texas Auto Trim on Bissonnet, but I'd like to look around for a couple more shops…

My side mirrors are already "swung out" and I have the concave blind spot mirrors. But I recently had close calls so I want an extra pair of "eyes" for my safety.
