Sounds like you have a bit of applicable experience. Write up a good professional resume (lots of on-line help there) outlining in detail what you've done and start shopping it to the companies needing junior HPT's. Be prepared to go anywhere for any duration for any amount of money and do anything your asked to do. Keep knocking until someone lets you in. There is an expected shortfall of techs this spring so it's a good time to try to get your foot in the door. Once on site hang with the folks who show up a bit early, work hard, and stay out of trouble.
