Don't give up, you'll find the right job. Use any contacts you have and just keep trying. Also, I can't say this enough, but make sure you have a great cover sheet that really sells you. My husband had several interviews just because of his cover letter. I graduated with an electrical engineering degree, worked a couple years with it, hated it, and finally found a job in engineering, but a completely different field. It's hard to change fields once you work a few years somewhere, but it can be done!
