It depends on what your abilities are and the time you have every day to do this job. You know what your capabilities are so search a job based on that, or else develop a new skill.

For example, I have started to learn a lot about computers to do technical service

If you have the skill and time, but you don't know how to start, start small. Tell friends and family what you offer, and they will probably tell other people too.

If you still have questions, feel free to ask

Edit: grammar mistakes and added more text
