Hello! Any advice to get a job like production assistant?

Hello! I feel a little struggle. I know we are living difficult times but I don't want to give up. I have been to London for one year, and after 5 months to come here from Uruguay the COVID appears! I have experience in the role of production assistant in Uruguay and I am looking for a possible position here. I am available to do work experience to get experience here too. Any advice or recommendation will be appreciated! Thanks!
