I'm on the advisory board for Otronicon, and heard that the science center is hiring Game Techs for that weekend. Pay is $10 an hour, and they expect technical competency with game consoles, basic hardware, etc.
Ping me if you are interested, and I'll put you in contact with them.
They also will need general volunteers for the event, but they aren't doing those signups yet.
FamiLAB will also likely get an invite and we will need volunteers to staff a booth, but if you can get paid for the weekend, why not
