Just finding out the common Pokémon in each place is probably a small tip her route. Finding out about the rarer Pokémon or potentially find one would be a considerable tip. Or you can haggle, it's a vague service, after all.

Anyways. Regardless, I don't think you updated your inventory and Pokémon after the fight with Cathia. I just went to check how much money you had due to going to the Explorer's Guide Service, and I think you have more than 22 P, and your Pokémon have gone up a few levels... Haha.
