Any places in Denton that hire people for just one day on the weekends?

I have a regular full-time job during the week and I'm looking to supplement my income but only looking to work one 8 or 9 hour shift on the weekend, either Friday night, anytime Saturday, or Sunday. All the places I've applied or talked to so far look for people who can work at least 2-3 days per week. Anybody know of places that are interested in someone working just one day? Thanks
