Can't help with a 'service', but there have been other threads started like this. The usual answer is to make sure the company is bonded, licensed, etc. and that they have experience moving a tank/livestock/etc.
You'll probably find your best bet is to do it yourself. Get some big stock tanks, transfer stuff into them to keep everything running/alive, move the tank, get it set up at the new location, and then move the livestock and such. Depending on how you did it you could reuse the water or just start with new water.
Also, if you stir up the sand bed you'd probably want to toss it, or at least rinse it really well before putting it back in the tank. You could save some to re-seed the tank along with your rock.
YMMV, but you might be able to get some assistance from some local CT reefers for gas/beverages/etc.
Good luck!
