How do I get a job online or physical as a teenager?🤞

I live in United Kingdom of Manchester and I want to try and get a job as a 15 turning 16 soon this year because I don't want to use my parents money to succeed on my future career on side hustles such as Content Creation, Investing, Trading ( I have learned trading 2 years ago from now and I would say I am an intermediate trader ) and Dropshipping, Soon to start Ecommerce.

My goal today is to get a job, save money & learn about finance. My only problem today is money.
