40F Looking for a legit side hustle that can make around $200 a day

I usually work from home and have some extra time during the day. I’m looking for a legitimate side hustle I can do online, ideally with flexible hours, with a goal of making around $100 a day.

What has actually worked for you? I’m not interested in MLMs, scams, or anything that requires a big upfront investment. I’d really appreciate real experiences and suggestions.
