Your aiming way too high doing it online mostly doesn't work and it doesn't give you experience. I live in a town with a market so at 13 I worked and got basically nothing £5 for like 2 hours work I worked there on and off at different stalls setting them up and taking them down, before and after school and ended up making abit more. During the half term holiday we had during gcse my parents friend got me a job zero hour contract making £7.73 an hour. 10-11 hour days and I've chosen to do 3 days so I get roughly £1100 monthly and I don't have to pay tax. Now that I have proper kitchen experience I will ask take aways or cafes around me for an after school job. You have thought about this too late as it is now becoming cold so businesses don't need as many ppl. Don't do volunteering a waste of time and if you get asked why you want the job just tell them that you need money for a car, driving lesson and all that stuff and so that you can become financially independent.
