What can I do to help me land a job?

I am trying to really get my foot in the door to work I’m doing what all the posts say, print my resume walk in greet the hiring or install manager, cold calling places , sending resumes through email but nothing is seeming to work. What other job could I do that would help me stand out to become a helper because all shops around my area (SoCal) want someone with 2+ years of experience and I only have a few months. Really need some guidance if anyone can please and thank you
