I don't know of any straight razor honing services specifically in So. Cal, but there are plenty of places that do it.
Look here.
In reply to your other posts, some people use 1k, 4k, 8k, 12k, etc synthetics from bevel set to finish.
Others use full natural stone progressions, and others use combinations. There's many ways to get there.
It seems a lot of old world barbers mostly just had 1 or 2 small stones and a strop.
Equipment now days can include pasted leather/wood/paper/felt/linen strops, polishing tapes, natural stones, synthetics, bonded or plated diamond. Pastes can be aluminum oxide, chrome oxide, diamond, CBN.
The possibilities these days seem endless, and there are forums with hundreds of thousands of posts dedicated to this discussion. Unfortunately, this is not one of them.
What razor do you have, and what does it need? Can you post pictures?
