Would be an original guide, 1st page of this guide shows the recommended cash holders for rerunning the islands for cash earning that is the closest to what you are proposing.
guide to money making multiple methods.
Only thing I see and it only has the cash earned from beating them, not the fully lvled up pokemon or 4-6 pokemon they all run. Don't think you need to worry about learning what moves they learn as well, that will just be too tedious for you.
As far as I can see, there is no guide for that out there and the bulbapedia guide has a few pokemon from the rematch, but not is what is currently in game now.
Would be a fun and useful guide for people that need help with lvl 50 pokemon, 1st step to make it popular would be the e4 and their scaling effect, pretty unique and recent to this MMO mod, so if it's not in this forum would be a good place to start. Might be good to figure out the moves from those pokemon.
