How to move a 700 lb fish tank with one guy?

I've been into the Salt Water tank hobby for about 10-15 years. Things sure have changed. I'm running a 90g display with a 30 gallon sump. I've swapped from metal halide lighting to LED. I changed over in October of last year and have saved over $600 in running costs.

Love my little piece of the ocean. However with the "Save the animals" people it's getting harder and harder to collect. But I doubt I'll ever give up. Kids love it, guests love it. It's easy to maintain. Mine is computer controlled. All I do is water changes and cleaning once a month.

I'd really like to expand my coral and fish but I'm out of room. Except for another couple small fish. Maybe a Flame Angel or something.
