You could try aquabid or ebay and make sure you state that it is for local pick-up only. Unless you want to ship a 75g tank and stand :lol:
You might want to list out what you have, as I see you have quite a bit of coral in there, any fish, how much LR/LS, skimmer etc., and whether you're willing to part it out or what? Just add some info, like are you willing to take a best offer?
