I'm pretty sure there's plenty he should give me, but I'm yet to see him because apparently he only shows up on clear days, and it's been raining almost every day since I got the game. =/

I hadn't seen Phineas for a while, but then all of a sudden... I got 7 badges in one day! For bronze, I've got the whole first row, plus the Island Medal, Gardening, Refurbishing, Cataloguing, Good Samaritan, and Representative badges. And because of some lucky investments, I have the silver Turnip and Saver badges. I... don't even know how I got all of those! I don't remember bribing Phineas...
