What quest will give you a lot of money and quest points

Well there was this quest i have done a while ago that earned me 50k and a good few quest points. In carraton on hare isle go to the rock shop, the owner is called Gray Slate, talk to him. he will be designing a crown for a king, he will ask you to bring him a good few items and they are quite expensive but it is worth it in the end! the quest isn't to long...the dearest item you will have to get is 5 diamonds and couple of rubies.

Well, for a free player...like me...the best quest that you haven't done yet would be the black knights fortress. It gives you 2.5k and 3 quest points. You can't be afraid of a level 33 black knight because if they see you, and you are around their combat level they will attack you 99.9% of the time.
the quest that will give you alot of money is called get off your but and make your own
