Whats a good P2P quest for me for Runescape?

I'm level 92, 80 str, (70k until) 75 attk, 67 def, 61 range, 60 magic, 53 cooking, 63 fishing, 46 thieving, 47 crafting, 45 prayer, 75 hp, 50 mining, 40 agility,56 wc, 45 firemaking, 36 fletching, 35 slayer, and 28 construction. The only two skills that are level 1 are farming and dungeneering. I have over 25 mil. I need a fun quest, medium length, with a difficult battle and a good reward. Thanks in advance, I'm sorta bored.
