Sorry but I only cheat to get pokemon from events. I could help you but it seems you are doing it for a short cut.
If you really want pokemon with perfect EVs and IVs to go against other people then do it here. http://www.pokemonshowdown.com/
Otherwise you are basically admitting you are awful and can only win with hacked pokemon against legit pokemon.
Why would I want to use them on the god awful wifi?
Then why do you want perfect IV's and EV's?
Nothing in the game can even get close to a level 100 pokemon with horrid EV's and IV's. You can't really do it for bragging rights because they are just cheated in and even with challenge mode active things don't get close to level 100.
