Having help move a beatmania, I can say that, assuming everything is screwed down properly, there's no problem putting it on its back or side and just transporting it like you might any other cabinet. I've moved a para para in the bed of a pickup with the stage in a minivan, worked fine. beatmania got moved in a large commecial van ("white van man" style) on its back.
Basically, get a vehicle big enough and chuck it in there. If possible, try to secure it in some way (especially in a pickup), but in most cases you can just go easy on the driving.
To move the cabinet itself around, find a dolly that's of a reasonable size and put the cabinet on it. Be sure to use a strap to secure it to the dolly. The cabinet will have casters, but they're really only useful on hard floors, concrete, or level carpeting. Getting it into the trailer might present a hassle depending on how high it is. If it's sufficiently low, tip the cabinet back into the trailer and then push it in. 2 people probably won't be enough to just lift and carry a full size beatmania (though possibly a mini).
That said, if it's 1100 miles away, just call up the North American Van Lines high value division. There's a gal who specializes in setting up arcade moves. NAVL has STI move it, and they do a very good job. In the end, it'll probably cost you no more than renting a truck and paying for gas, and somebody else will handle it for you. They'll even help you move it into your residence if no stairs are involved.
Are you by chance purchasing this from an arcade in Bloomington, IN?
