If there are truly no changes to plumbing and electrical--and I would be very surprised if that's really the case unless the kitchen was redone relatively recently with permits and you're only changing things aesthetically, since CA code has a lot of specific requirements for kitchens--then you can do this relatively affordably if you're willing to piece out the elements (that is, hire someone for the demo, someone else for the drywall, someone else for the tile, etc.) It will take longer than working with a GC and you'll have to manage the project, but is considerably cheaper. We did this for our kitchen in the SF East Bay many years ago and I'm happy to share names of some of the people we worked with who are still around if you PM me. We had the cabinets and counters installed by the cabinetmaker and fabricator, respectively. We hired a plumber, electrician, and drywaller directly. We did the floors and painted ourselves (though could easily have outsourced those too). We did the plans and pulled the permits, so it was on us to make sure everything was to code and that we purchased the right supplies and materials. (We did opt to pay a kitchen designer hourly to review and give feedback on our plans, in addition to many many posts on GardenWeb, to be sure we weren't missing anything, and I definitely recommend that if you do a project like this.) All of that takes time, which is a lot of what a GC is charging you for (that, and relationships that will help your project get to the finish line more quickly).

We are finishing a bathroom project using a GC now, though, and there have been just as many (more?) hiccups with that project as with the kitchen. The only real distinction is that it's on the GC to fix, not on us (e.g., we just had our final inspection and had corrections to make, so I texted him the list and that was that--with the kitchen we had to call the electrician back to ask and pay for a change, etc.)

Raw material costs are up right now and there are still some supply chain issues. I found it helpful for our bathroom project to slowly collect what we needed as things went on sale, so we had a garage full of pieces for many months.
