Saturday condo cleaning can be the most lucrative part time job if you hook up with the right people who are willing to pay. I've known people who make $200-$300 a Saturday during the summer season because they're paid a nice sum per house/condo rather than an hourly rate.
Your experiences may vary, or course. But since it's work that not a lot of people like to do, it frequently pays significantly better than flashier, more mellow jobs.
Queen Bee Cupcakes is a new cupcake shop that will be in an Airstream in Seaside. With an open window to sell out of, maybe that will fit your outdoor requirements. Let me know if you're interested.
