Find a business that could use one of your projects to solve one of its main problems. Then get a meeting with somebody there who has the authority to hire you (this can be done simply by email, but it helps if you have some common connection with them), go to them and show them what you have made, explain how it and you will help their business, then ask for a job. Do this a bunch of times and you should be hired somewhere.
