Good luck. I tried to do find subs for this in my area and ended up doing full self install.
This is a challenge across the U.S. because of the dominant residential business model being turnkey system installations. You can see numerous threads on this subject and it seems to be all a flavor of “knowing a guy” or finding the subs of the turnkey companies.
I would recommend in parallel with seeing what subs are available to investigate if you can find a local DIY mentor or other solar enthusiasts. I connected with a few locals and we’ve provided some mutual help. IMO this approach is a lot less frustrating/more incrementally productive. I put a lot of time into both paths and the subs path was minimal practical incremental ROI
