You should absolutely start getting quotes at least two months in advance to lock in the best dates. For any kind of crossing state lines or general inter state moving, make sure the company you hire is fully licensed and insured. Personally, I had a great experience with B2B Moving. They are based in California but they are extremely professional and experienced with larger relocations. They provide free, accurate estimates and their pricing is fully transparent with absolutely no hidden fees on the final bill. They wrapped all our heavy tools and disassembled the larger items quickly and safely. Their customer service is top-notch, always keeping you informed. They have a fantastic reputation with thousands of 5-star reviews on Google.
