Job? ?

Question

I'm 20, still in school and would like an after school job. I dont like the ideas of giving up the only free time I have (Saturdays) and I will have no choice but to work next year so im just looking for a job I can do after school to earn a bit of money. So does anybody have any ideas of what I can do? Please don't say paper round haha I mean an actual job.
Thanks!
