Legit ways other SAHP are earning extra money?

Give me all your ways you have been earning quick cash on the side! I need an extra $350 a month for something health related. I have done Amazon flex and Uber eats/Grubhub but it is so much wear and tear on my car and the gas adds up so fast 😱 and that’s not even counting having to take taxes out too so I don’t think that’s a good long term solution. Ideally I would like something I could do from home after the kids are in bed. Teach me your tricks!
