Well for 800 gold per account, you should be able to get some greens from the AH. You could post an add on your realms forum that you are looking for some cheap greens. Instead of selling them you could get them.

Another probably faster options is to run utgarde keep a few times, Maybe get some cheap crafted for the tank first. It's a matter of 2-3 days biting he bullet and you are geared for your level again. I even think you can get away by multiboxing naked while questing, thus pick up where you left. Mounts gone sucks of course, though there are some very cheap ones in the game available.

Nothing wrong with sending a gm an ingame ticket, and saying you want to renew / upgrade your 7 accounts again, but that 800 gold per is not going to cut it for you. The prefer giving you more rather than losing a player with a genuine case (that saved them time and money by giving you the dontwhine package) who pays for 7 accounts and is about to upgrade to cataclysm. If they don't bite, try again. So far I got what i wanted whenever i reopened my ticket (though i had a 'valid' case, it just takes some effort to persuade them). Same goes for calling them again though. I've read stories from boxers who got free authenticators after calling with CS.

You have a no, you can get a yes.
