This past July I moved my 65g from VA to NC. In half a day I removed rocks into 5 and 10g buckets, lowered the water level to about 5-6 inches to make it easier to net the fish, netted the fish and put them in the buckets with the rock, tuand used a $25 Bucket Head shop vac to remove the remaining water and my 4" sand bed. Loaded everthing into the SUV, drove down to NC that night, and put everything into a half-filled 100G livestock tub as a temp home for a 2 weeks while I got the tank set back up.
You could do the first half of that process to get your new stand in place...
Empty everything into buckets/tubs. Get a friend or two to lift the tank off the old stand, put the new stand in place, get the tank on it, hook all the plumbing and gear back up, then put the livestock back into the tank.
If you need a little extra time to 'breathe', pick up some cheap hydor heaters and some $10-$15 battery powered airstones and put them into the buckets/tubs to keep your livestock comfortable overnight until you can the the tank set back up.
