Run to the next area. Just at the beginning you'll see a Lucky Man on the right talking with a seeq [screen 1]. Talk to that man - he'll tell you in a great secret that he has found a lot of money in a barrel. Next go talk with Beasley - he's sitting a bit farther [screen 2]. He'll tell you that he has hid all of his savings in a barrel. Run towards the entrance to Archades.
You'll see two guards on the stairs [screen 1]. Talk with the one on the left. He'll ask you about the credentials. You don't have them so it doesn't matter what you tell him they won't let you in. Then Jules will give you a hand... well not for free obviously. He'll ask you for 1500 gil. Unfortunately you have to pay him up. After you did that run and talk to Beasley once again. Get back to Jules (now he's sitting on a crate, on an intersection [screen 2]). After the cut-scene you'll find yourself in Archades.
