I broke into teaching through substituting. I had to do it about a year, and then something came open in middle school. We don't have any elementary openings around here either unless everyone knows you, but middle school is pretty open and so is high school. You may want to look into getting a Master's in a field like special ed or get a additional endorsement in something that is in demand. You could also get additional coursework in a high school area like math or a foreign language.
Another note: This is going to sound biased. Watch what you wear and how you act around the students and at interviews. Piercings, tatoos, wild funky hair, crazy clothes, and poor oral language skills are all turnoffs to the older people doing the interviews. While that may not be "fair," that is the reality of the professional world. Most places still want good, clean, conservative role models for the students. We have had several teachers hired/fired that acted more wild and crazy than the students. They ultimately end up not getting rehired. The students may be interested in seeing your "whatever," but the school administrators are appalled when you show "it" to the students. Just be careful and get to know the attitudes and personalities of the people in your system as you try to get hired.
The last person not rehired at my school was a mess. Her English was awful, she dressed sloppy and just like the students; we frequently got to see her bare abdomen, and she stayed all wrapped up in the students emotional problems not to mention she couldn't write and follow through on her lesson plans. She was let go at the end of the year. While none of this may apply to you, take it with a grain of salt. Good luck. Teaching is one tough profession, but I don't ever want to do anything else. I love it!
