With the new no-tax-on-tips laws in effect, bartending may be a decent option. Although I hear it’s only tax free on the first $25k/year, so keep that in mind.

Other than that, maybe try marketing some high quality goods at a local farmers market. I went to mine recently and found out that a local farmstead was able to save their farm by selling honey & olive oil-based soaps, candles, and shampoos.
