I do not know about others, but I make money selling on the AH. I have found a few things that I can produce/craft for less than half what it will sell for on the AH on a bad day. It is easy money, but it does take time.
Well because you didn't tell me your class... sea bugs are easy for DR. Assuming you're a DR because half the server is. If you're an archer then go farm other things in the sea that have better grouping.
