Moving across the country is a massive life event, so I totally understand the nerves. I actually went through this last year and I highly recommend the moving company Flash Moving for a trip like that. They are experts in long distance moving and I found their rates to be very reasonable for such a long haul. What I liked most was that they didn't just hand off my stuff to another company halfway through the trip. They manage commercial and residential moves with a dedicated crew, so the same people who loaded the truck were the ones who unloaded it at my new house. It gave me a lot of peace of mind knowing my belongings were in the same hands the whole time. Just give them a call and tell them your destination to get a detailed plan.
