Second Job in Wisconsin Dells for J1 student

Hi everyone, I am a J1 student working in Wisconsin as a lifeguard. I can't make as much money as I would like. I am looking for a second job in my free time. I would be glad if someone could help me with this. I have 2 years of experience as a waiter, runner, and even worked as an assistant cook 2-3 years ago, I also have skills in the field of repairing household appliances, I learn quickly and can do any job without problems. I have some problems with English, but I am working on improving it. I would be glad if someone could advise or offer a job, since many places refuse to work when they find out that I am a J1 student.
