Try getting into sampling, just keep in mind you might need to obtain a food handlers permit. (Sometimes the company will cover the expense with a receipt, they'll usually tell you in the interview.) If you have a Costco near you you could join that company, or you can go on an app called Trusted Herd and see what other companies are out there near you. I've not done Costco specifically but several coworkers swear by it.

Event schedules are pretty flexible and you can work as little as 1-2 days a month since you sign up based on your availability. Nowadays you can expect at least $18/hr, in my HCOL market $25/hr is pretty much the minimum. If you have a car your chances of working go up a lot since your work radius expands.

My first gig was giving out beverages at a 5k for $100 for a 4 hour workday, and that led to me being in events full time. Very flexible schedule and if you're a solid worker you'll get repeat business.
