Work on your portfolio. A few of the biggest factors of landing jobs as a freelancer are:
- Communication & transparency. - be upfront about the cost of your services and how long it'll take to complete the project.
- Previous work & reviews. - People need to be able to view your portfolio. If you have nothing to showcase, do some javascript/python projects from youtube & showcase them on your portfolio.
- Visibility. The more people you respond to/submit a proposal to, the higher the chance is that you get a job/contract.
