I recommend Atlas Vanlines for that kind of stuff. I am in the moving field and furniture pads are definitely the way to go . Not only do they protect the glass from scratches but they also give the whole piece strength. I also recommend using a piano skid on each end (strapping the piano skid) And a few 4 wheel dollies . The piano skid will also give it strength as well as it distributes the weight a little bit better rather having it on a dolly which are technically only for so much weight. If you do decide to hire movers make sure they are international and very well trained. There are a lot of sketchy "make money quick " movers and the reason why I recommend atlas is because 85 % of the time these people are traind, insured and the company will be held accountable for damages not only to the tank if something does happen during transport but also any damage done to property.
