Out on the beach killing Eremites for a Yutto called "The One Loved by The Sun". He gives you this quest to go kill 5 Shell Eremites and he will give you cash. I am not sure how much he gives you due to the fact I logged off shortly after I killed two of in the picture above. The place is close to North Elysium on the beach by the Enel Shrine and Shere Shrine where the Yuttos are.
There is a place you can enter here where there is treasure and some mobs that give good xp. I picked up alot of nano and health coils from here. If you are low on cash and need some go here to get your loot full.
