Really? Northern Cal?
Download the Thumbtack app, enter your electrical need with a couple pics and within a couple minutes....you'll have a couple electrians giving you quotes.
Also Offerup under services....less immediate though. Both apps work on older Android and iPhone devices too.
I went to Angies. It gave me four electricians to choose from, and I heard from one, one of those who subcontracts out to a gigantic list of subs. They can find someone, I am sure, but ChatGPT said to be cautious about who you get. THEN, they gave me another list of 11 contractors, and knowing the situation, I asked for bids from all. I never received a bid from any of the 11.
So, there you go.
If you want to be an electrician, first see if you can find a trade school that has instructors!! Instructors are hard to find.
Then, if you can get through the courses, you are in the game. P=V*I (Power in Watts) = V (volts) * I (current in amps), or V = I * R (resistance in ohms), P=I**2 * R, etc.. Of course, as an electrician, you will need to know how to avoid electrical shock and other safety measures, so safety is a huge issue.
When I was in the Army, I went through their schools for "Nuclear Weapons Electronics" (aka 35F or 35-Foxtrot) So, I know something about electronics. In the end, we worked with the equipment they hooked up to nuclear bombs, SADMs (small tactical nuclear devices), and most of all, nuclear missile warheads, mostly hydrogen bombs containing tritium gas - that would infrequently escape into the disassembly rooms, setting off alarms - and they were constantly drilling evacuation procedures. And we would often have very large convoys transporting nuclear weapons around Germany - and everyone would get involved, as occasionally there were traffic accidents, .... The test devices were controlled by relay switches that would run different types of currents through various cables and circuits to verify that the explosive device circuitry was intact: Either that the circuits were not corroded, disconnected, or re-wired, or that triggering devices were triggering detonation at the right altitude, and so on. The SADMs were small bombs that could be placed in a backpack or canister, parachuted, or otherwise infiltrated behind enemy lines to be placed under bridges or other vital structures (special forces used them). This general info is declassified and you can find it on the internet or ask ChatGPT about it. FYI, the 35F's didn't directly use the test devices on any warheads (that was the role of the "55G's"). They tested and repaired the test equipment!
I wouldn't mislead you into thinking that electricians are all rich or anything. I think for a job that takes 4-8 hours, is low to medium difficulty, a homeowner will probably pay $500-$2000, depending on where he is located, the specifics, and, in particular, how fast they need it done. If you are running your own business, that is a reasonable fee, especially if you can be choosy and avoid less profitable jobs.
