Lvl 51 Fishing

Yesterday I got my first skill to 50 - Fishing. But I didn't stop fishing lobsters because I wanted to get 1300 lobsters and sell them on GE for around 500k. Today I got my fishing to 51 and have 260 lobsters in the bank. After achieving this, I'll try to do the only non-members quest i haven't completed - The Dragon Slayer.
