Hi Katie,
Great size tank, I love my 215-gallon myself! Must be pretty exciting to get it!
Since it sounds like a fully functioning, currently running tank, I'd probably suggest having the pros move it.
I believe Timfish on ARC can handle that if he's not too busy or you can usually hit up one of the LFSs for a quote to move it.
Most of the time when we get a bunch of people together to move a tank is when its empty. There's just less logistics to worry about and try to keep track of so anybody can just show up, grab a corner, and lift.
The last full tank breakdown, move, and setup I was part of was a disaster as most of the corals died and fish as well. The person didn't prepare anything before and didn't have new water ready at the new house. We did our best to transport everything safely but without proper planning, it ended up as you could best expect. Plus, it also took up all the volunteers day up. Something we thought was going to be just 2-3 hrs ended up being an almost 6-7 hr day by the end of it. I'm all for always pitching in to help but an almost 8hr day is more of a job than just trying to help.
If you do want to still tackle it yourself, perhaps you can get over there and get the corals and fish first and then have volunteers help lift and move an empty tank later on?
Hopefully OceanTraveler chimes in here as she just paid people to move her tank not too long ago.
