A few things come to mind:
I think that there is a Kashima Shinryu group that meets at the UCLA campus. You might want to check them out; Kashima Shinryu is a koryu that practices kenjutsu as well as iaijutsu, jujutsu, naginatajutsu, sojutsu, kusarigamajutsu, etc. You can find some videos of the style on youtube.
If I remember correctly, the main Suio Ryu dojo for the US is in that general area. Like Kashima Shinryu, Suio Ryu has a curriculum that focuses on the sword but includes several other things. Some video of their stuff is also on youtube.
Both Kashima Shinryu and Suio Ryu have websites for their dojo.
Finally, I've heard that there is some Itto Ryu kenjutsu out in LA. There doesn't appear to be a website for this group, but if they are out there, I'm sure you could dig them up with some effort.

My opinion is, in all likelihood, worth exactly what you are paying for it.
