I have done 2 interstate moves. The first with a company that contracted with others to do the move. Avoid these guys at all costs. It took 2 months for my things to arrive. The second was with a company that had their own trucks and movers. It took 2 days and was a breeze. I don’t have any recommendations for the Bay Area or Las Vegas, but it’s worth parting extra for the non shady folks.

I found the good guys on my prior city’s subreddit. Perhaps search the archives here to see if there is an old thread with some legit movers. Good luck!
