If you play Runescape, I would recommend starting a free/cheap skilling or questing service. If you don't play Runescape, but rather, play other games, think of ways to offer free/cheap services to people in those games. Once you acquire some vouches, you can then start charging more money for your services due to you have reputation.
You may also consider donating to act as a catalyst in the entire process. Donating with the money you end up earning from your services may be a wise investment if you decide to stay here for the long run.
Good luck.
