Earn money on the side – where?

Hello,

I'd like to earn a little extra money. I already have a mini-job, but I still have some free time on the side. I have a student job where I get reimbursed, but it's very irregular, and it's not peak season anymore, so I was wondering if anyone knows anything about it and knows where I could look.

Are there places where I can help out from time to time? For example, at events or just somewhere where I can help out from time to time and earn a little extra money? I'll be helping out at an event soon, but unfortunately, I rarely see any job postings like that.

Does anyone know where I can look for something like this? Just a little extra cash now and then. I don't like sitting at home on my days off and would like to save a little.
