Pokefind should add one command that allow trainers to add items to auction in the auction house and one command that allow trainers to bid on the item they want.
I like your suggestion pal! This would be a big change to PokéFind but the only concern I have is that it could possibly cause scamming, I would only specify - Pokéballs, Lucky eggs and rare candies to be only auctioned as auctioning pokémon would most likely attract scamming to a whole new level.
The IV's are not always shown for people and they could mislead information about whatever they put into the auction house. Its a good idea but it has its flaws.
Like as @ShootingFor3 mentioned, IV's are not always shown unless there would be an alternative way to do this thing in the future, most scams are also involved with misleading IV's
