Yeah sure, I can help you.

You can receive Clue number 1 as a gift, or prize after you beat the Bounty Hunt quest. After you beat the quest, just talk to the woman and you should receive your prize.

You can get Clue Number 2 after you complete the Lost Trader quest in the Dark/witch woods. Talk to one of the traders in their camp and you should receive the treasure clue from one of them.

You can get Treasure Clue number 3 after you kill all of Twinblade's Assassins'. You can find one on the last windmill on Windmill Hill. One in Knothole Glade, one on the prison path near where you get locked up, and another in Hook Coast. The last Assassin can be found at the Witchwood Cullis Gate. Kill them all, and the last one will have a clue for you.

To get the 4th Treasure Clue, talk to the man outside of Knothole Glade. The one that runs the Archery Game. Now, you can either beat the high score, or kill the man. Either one of these is guaranteed to get you a Treasure Clue.

The Fifth treasure clue is in the Orchard Farm treasure chest. Just look near the haystacks, or near the farmhouse and you should see it, nothing to it.

The last Clue is back on Windmill Hill, on the last Windmill. Go up to the second floor so that you are on the roof. You will see a treasure chest that contains the last clue.

Hope this helps.
