I mean, going door to door and asking won't hurt. Give them a quick sentence how you're saving up for something and if they need any help around the house. Lawn mowed, dogs walked, etc. If they say no, thank them for their time and move on.
You could also go to a mechanic shop, fencing company, really any random trades shops with a resume and ask if they need some help around the shop.
I finished college and took me awhile to get a job. Walmart, McDonalds, and the like never called me back. Took a job as an L1 support for some startup and moved up to SysAdmin.
How'd it go?
