Hey someone pls help me

Hey so I'm from a tier 3 city and I'm just gonna turn 18 and the thing I wanna ask is like where to find a job so currently I live with my mom,my dad died when I was 13 and I don't wanna see my mom provide for me anymore I wanna support her plus pay my own bills. But all of these platforms are so saturated like linkedin and all so someone tell me where to get a remote internship even if it pays less I want experience in my portfolio so pls pls help me and also I'm good at management things or anything related to finance and I'm willing to learn anything related to that(tho I'm a bio student)
