Hello Yarael, I could be in use of your services. I think that the RPG value in alot of servers is completely lost, and people only worry about their level and who is on the high scores.
On the server I am making, I have great ideas, but not so much the ability to write out stories like you can in your example.
Here is one quest that I am working on making in my server.
The whole idea revovles around a knight, a woman with whom he was in love with, and a jealous wizard. The quest starts out with an NPC telling you a legend about a monstrous tree deep in a dark forest, that lashes out, and attacks all the people who come by it. The next part of the quest involves you going into that forest, and finding a tree monster named Trent. When you kill Trent, you loot two things, a key, and a piece of paper telling a story about how he was going through a walk through the forest with a lovely lady, when he was attacked by a mighty wizard who wanted to make the girl his own. The knight and the wizard fought, but the wizard came out on top, and trapped the mans soul into the tree.
The note also tells you about the whereabouts of this wizards keep, which is actually at the edge of the forest. This is where looting the key makes sense, as it allows you to open the gate to the wizards keep. When you enter the keep, if you first go into the dungeon, you will find the woman with whom the wizard kidnapped, and she will ask you to kill the wizard, and set her free.
Pretty standard type of quest, but what I would ask of you is to give it more flare, make the npc dialogs more interesting, the whole story have life, and more detailed.
Please post back if you are interested in helping making this story/quest, and whatever type of payment you would be interested in.
