Looking for bag recommendations

Sorry if I'm being picky or too specific but I'm looking for a bag with a square/rectangle insert. (I'm looking to make a ship bag and I want them to be even on both sides) I'd like one that has key chain hooks on the inside of the bag. I'd prefer if I could find one with atleast 2 hooks on the inside. I'd like an over the shoulder bag, I don't need one with a lot of storage I'd be happy if it was like a tote bag. Sorry if this was confusing, I'm new to this stuff and this would be my first ita bag
