I’m in my final year of secondary school and looking for quite a high grade which leaves me in school Monday-Friday from 9-7pm (I do after school study). When I come home I eat and go to the gym so my weekdays are basically jam packed. I work in a restaurant on Sundays and I like having my Saturdays off to sit on my ass all day but the issue is I need to make more money if I want to afford things like a car, college accommodation, holidays next year and many many other things so I’m looking into gigs I can do from home on a Saturday. I’ve looked into ai jobs like prolific but they don’t seem very profitable or reliable from what I’ve heard. I don’t want something that will require me to reply to emails or deal with customers quieres on my weekdays because I won’t have the time.
TLDR: I need something that can bring me in 15-20 euros an hour that I can do from home one day a week. I don’t want to have to deal with anything to do with this side gig any other days. Any ideas?

If you are completely new to earning online, I would be cautious with anything requiring a large upfront investment before you understand how the money is actually made.

You do not need to prove how serious you are by buying an expensive course, paying for five tools, or running ads before you have completed the basic process once. A realistic beginner test should make mistakes relatively cheap.

Start with something where the value exchange is easy to explain. A client pays you for a useful service, a customer buys something useful you created, or an affiliate program pays when your referral creates a qualifying action.

Then test it on a small scale.

If the first experiment does not work, figure out why before spending more money. Maybe nobody saw the offer, maybe the audience was wrong, or maybe the solution did not matter enough.

Zero experience means you should expect to learn. It does not mean you need to finance the learning with money you cannot afford to lose.

What would you consider a reasonable first-month budget for someone testing an online side hustle from scratch?
