Some players are very busy and would rather pay someone to gather the items they need or want instead of doing all the work themselves. With some jobs, you may even gain a few levels, such as killing cows and gathering their hides. The more you kill the more levels you gain along with more money.
A cook is more of a fast-paced job, while a farmer is more calm and relaxing. My favorite spot to farm is north of Port Sarim, behind the cabbage patch. If you were to stand outside the house portal and offer your services such as buy runescape accounts, then you might get hired as a cook or some other type of help. The bigger the house is the richer the player will be.
One of the main things you will be making is tea. It's fun and easy to make. Another good item to make is Scrambled Eggs. Take an egg and a bowl. Put the egg in the bowl and cook it. Cakes are also good.
You could also try to become a thief and steal from the computers. Nevertheless, once you get past pick-pocketing, move on to stalls. You can make a lot more money with stalls than pick pocketing. To save time, farmer100 has awesome runescape accounts for sale!
Enjoy gaming time and make money in runescape!
