For some reason Valencia/Santa Clarita has very limited options. It's a shame too as there are plenty of hobbyists there that would love to not have to go over the hill to meet a quality provider. A hot provider could make a $$$ killing there if they serviced the area. That said, I assume there are reasons I'm unaware of for the lack of options. Maybe it's too far, LE presence, or ....?  

Good luck finding what you're after.
