This is a thread for anyone who has a job recommendation for Seph, I'll start:
Seph if you live in the U.S. (and maybe if you live elsewhere) I can personally attest that selling boffer weapons (https://en.wikipedia.org/wiki/Foam_weapons
) at Renaissance fairs can be very lucrative; their easy to make and the cost of materials (where just talking PVC and pool noodles and duck tape here) and booking fees (50$ to 300$ usually) for smaller shows is generally cheap.
since you sell it yourself, and most of the income is in cash I'm sure you'll realize certain implications apply.
all in all, you can usually net around 500$ to 2000$ profit per show, not bad for around a week of work.
if you're not from the U.S it might still work but you'de have to look into the particulars.
