15 y/o wants side hustle ideas

I just recently had a realization that i need money, in the ballpark of 4k by this time next year. I will have plenty of free time up until the end of summer, then i'll be busy for the rest of the year. I have $200 saved right now, and at least $500 in junk that i don't really care about anymore. I can't get a job, the only place that hires people young as me is extremely overstaffed and denied my application. I don't want any online stuff like drop shipping or those surveys. I don't have a car but I can bike places. I was just wondering what kind of thing would work for my circumstance. thanks in advance
