There is no better suggestion, there is no ingame way to automatically go through 70.000 items.
Regarding the EULA - why not ask SOE if they would have a problem with that. Pasting and clicking an item link is not exactly like unattended game play, so they might allow that. Send Grimwell an email/PM and ask. Or ask your colleagues how they do it, not sure how hard the competition is with them and if they would tell you.
