For $1700, I would just buy a new one. I can't imagine it would be much cheaper for someone to dismantle that and rebuild it for less. And, then have to worry about it being built correctly.
Next time, build a makeshift stand with wheels if you have the means. Then you could just wheel it wherever you need it. The only lifting you will have to do is from that stand to the permanent one. This is what I did to move my large tank around. I mean, if no stairs are involved anyway. Pic below for example.
Also, if you decide to use that aquarium, I do not believe that little chip will hurt the integrity of the tank but, I would definitely defer to a tank expert (Joe w/Glass Cages for example) or IM for sure.
